The Waterfall Model in software engineering is one of the earliest approaches to software development. It follows a strict linear sequence where each stage must be completed before moving to the next. While it is simple and well-structured, it also has several limitations that modern methodologies attempt to solve. The Waterfall Model is a sequential software development process. It was first introduced in 1970 by Dr. Winston Royce. The model is called "waterfall" because progress flows in one direction, similar to a waterfall, without going back to previous phases. The development life cycle under this model usually includes: Requirement Analysis – Collecting and documenting all project requirements. System Design – Creating architecture and design based on requirements. Implementation (C…  ( 6 min )

Learning a new skill is never easy; and programming has proven to be one of the hardest challenges I’ve faced. I began my coding journey in 2024 when I joined ALX, knowing nothing but eager to write those magical lines of code that bring apps or games to life. But reality hit me very fast. We began with Shell basics, which were smooth, then moved to C language, which humbled me. Starting C, I thought: “If I can print Hello, World!, then I can do anything.” On came about functions, pointers and arrays which didn’t just confuse me but crush me to the pits. Instead of truly learning, I took shortcuts: copying code just to pass. Soon, I was drowning in recursion, data structures, and memory allocation without understanding the foundations. By June 2024, I knew I had to take a step back: I felt guilty, defeated, and convinced maybe programming wasn’t for me. Still, the dream never left. After months of reflection, I realized the first thing I needed to fix wasn’t my code; it was my mindset. Now, as I restart my journey, I come better prepared: mentally, emotionally, and practically. I know there will be long nights of debugging. I know errors will test my patience. But I also know this: quitting isn’t an option anymore. This time, my path is clear: Progress >>> Perfection.  ( 5 min )

When most people imagine Data Science, they picture building shiny machine learning models or crafting beautiful dashboards. if your data is messy, no model can save you. That’s why people say: “80% of a data scientist’s time is spent cleaning data.” And it’s not a joke. Missing values → blank cells, NaNs, or inconsistent entries. Duplicates → one user recorded multiple times. Outliers → extreme values like a salary of $1,000,000,000. Inconsistent categories → Nairobi, NBO, 254-Nairobi treated as different. Wrong data types → numbers stored as text. Here’s how I usually tackle some of these: import pandas as pd # Example dataset data = { "Name": ["Alice", "Bob", "Charlie", "Alice"], "Age": [25, None, 37, 25], "Salary": [50000, 60000, 1000000000, 50000], # notice the outlier "City": ["Nairobi", "NBI", "254-Nairobi", "Nairobi"] } df = pd.DataFrame(data) print("Before Cleaning:") print(df) # 1. Handle missing values df["Age"].fillna(df["Age"].median(), inplace=True) # 2. Drop duplicates df.drop_duplicates(inplace=True) # 3. Fix inconsistent categories df["City"] = df["City"].replace({"NBI": "Nairobi", "254-Nairobi": "Nairobi"}) # 4. Handle outliers (example: cap salaries above 200k) df["Salary"] = df["Salary"].apply(lambda x: min(x, 200000)) print("\nAfter Cleaning:") print(df) Before Cleaning: Name Age Salary City 0 Alice 25.0 50000 Nairobi 1 Bob NaN 60000 NBI 2 Charlie 37.0 1000000000 254-Nairobi 3 Alice 25.0 50000 Nairobi After Cleaning: Name Age Salary City 0 Alice 25.0 50000 Nairobi 1 Bob 25.0 60000 Nairobi 2 Charlie 37.0 200000 Nairobi Don’t ignore missing values, understand the why before filling/dropping. Standardize categories early to avoid “ghost” groups. Outliers may be errors or real rare events, investigate before deleting. A clean dataset can outperform a complex model trained on dirty data.  ( 6 min )

Early-stage startup founders live in constant motion such as pitching investors, refining products, and fighting for traction. In this hustle, customer relationships often take a back seat. Yet ignoring them early can be one of the costliest mistakes. Three reasons stand out: Acquisition costs are rising. Customer acquisition cost (CAC) for SaaS has jumped more than 60% in five years, making paid ads unsustainable. Investors expect clarity. By Seed or Series A, you need metrics like CAC, LTV, churn, and funnel conversion. Without a system in place, these numbers are messy or missing. That is why customer relationship management (CRM) must be seen not as software you buy later, but as the foundation of growth. Whether you’re in SaaS, FinTech, HealthTech, or Energy, CRM ensures every lead is…  ( 8 min )

ℹ️ Re-posted from stripe.dev While working remotely and traveling from place to place, I noticed a recurring pattern. Every time you arrive in a new city, you rent an Airbnb or check-in to a hotel. Then you sign up for a gym and a co-working space. Payments for these services are all done electronically. But when it comes to access, you need a plastic card, a fob, or a physical key. This creates friction for everyone involved. You have to go pick it up, carry it around, hope you don’t lose it, and return it before leaving. From the business side, they need to pay someone to work the front desk to issue, track, and collect these access devices. This made me wonder, what if access was fully digital? Luckily, there is a better way that is gaining popularity. Instead of cards and keys, w…  ( 9 min )

A JavaScript engine is a program that converts JavaScript code into a Binary Language. Computers understand the Binary Language. Every web browser contains a JavaScript engine. For example, V8 is the JavaScript engine in Google Chrome. Let's dive in! Execution context: Execution Context is the environment in which JS code runs. It decides what variables and functions are accessible, and how the code executes. It has two types (Global & Function) and works in two phases (Memory Creation & Code Execution). Global Execution Context (GEC) This is created once when your script starts. It's the outermost context where: Global variables and functions are stored this refers to the global object (like window in browsers) Function Execution Context (FEC) When you call a function, a new context …  ( 9 min )

The Enigmatic 'this' Keyword in JavaScript JavaScript's 'this' keyword is a source of confusion for many developers, but unraveling its mysteries can lead to a deeper understanding of the language's inner workings. Global Scope When used in the global scope, 'this' refers to the global object, which in a browser is the window object. console.log(this === window); // true Object Methods Within an object method, 'this' refers to the object itself. const person = { name: 'John', greet() { return Hello, ${this.name}!; } }; console.log(person.greet()); // Hello, John! Constructors When used in a constructor function, 'this' refers to the instance being created. function Car(make) { this.make = make; } const myCar = new Car('Toyota'); console.log(myCar.make); // Toyota Event Handlers In event handlers, 'this' typically refers to the element that triggered the event. document.querySelector('button').addEventListener('click', function() { console.log(this.textContent); }); By understanding the various contexts in which 'this' is used, developers can harness its power to write more effective and efficient JavaScript code.  ( 5 min )

Intro In one of my previous posts, I wrote about features between Java LTS versions 21 and 17. Now, two years later (how!? Two years already!?), a new LTS version is scheduled for release on September 16, 2025 — Java 25. Today, it has moved into the "Final Release Candidate" phase, and the feature set is frozen. The vast majority of projects skip non-LTS releases and use Java LTS versions only. So, let's take a look at the features that the new LTS version (Java 25) delivers compared to the previous LTS version (Java 21).

Software development is often portrayed as a purely logical discipline, one where success is measured in clean code, robust frameworks, and seamless deployments. Yet, anyone who has spent time working on a team of developers knows that the human side of the profession is just as influential as the technical side.

If you've ever pushed a change to production and your browser stubbornly kept showing you the old version, you've experienced caching, probably not in a good way. HTTP caching is one of those topics that can seem deceptively simple ("it just stores stuff locally"), but the details matter. Done right, it makes sites feel lightning-fast and reduces server load. Done wrong, it causes confusing bugs and outdated resources to linger. This isn't a deep dive into every caching strategy, it's the quick, developer-focused overview I wish I had when I first started building for the web. At the end, you'll find resources for going deeper. Fetching resources over the network is slow and expensive, not just in terms of latency, but also in wasted bandwidth and server strain.

I’ll be honest. Few things are more frustrating than solving a problem by reaching for a great package… only to realize the problem is still there. That was me last week, yelling at my API like it had just spoiled the finale of a Netflix show. I was using Spatie’s Laravel ResponseCache package. It’s rock solid, it works out of the box, and it’s built by people I trust. But here’s the kicker: I turned it on in production and suddenly my multilingual API was speaking one language only.

As developers, we spend weeks (sometimes months) training, fine-tuning, and deploying AI models. But here’s the uncomfortable truth: Once they’re live… do we really own them? On most platforms, your AI ends up locked inside someone else’s infrastructure: Behind APIs, you don’t fully control Running on servers you don’t own Generating value that mostly flows back to the platform, not you That doesn’t feel like ownership. At haveto.com, we think your AI should be more than just code. Here’s how it works when you deploy AI directly on-chain with us: ✅ Your AI gets its own wallet → it earns every time it completes a task. ✅ On-chain identity → proof of ownership is transparent, forever. ✅ Portability → sell, lease, or license your AI like a real IP. This isn’t “another hosting service.” Deploy AI on-chain, earn directly from users, no middlemen. True IP protection — no one can copy-paste your model into their cloud. Cost efficiency — gas fees drop as usage grows (a real economy of scale). You’re not just pushing code anymore — you’re creating revenue-generating IP. AI runs directly on the blockchain (no third-party servers). Transparent + verifiable outputs (great for finance, healthcare, and other trust-heavy domains). Secure, scalable, and designed for real workloads. 1️⃣ Build your AI model in any language (Python, JS, Rust, we don’t force you into one). 💭 Question for the dev.to community: 👇 Let’s discuss. 🔗 haveto.com  ( 6 min )

Developers love the rush of getting something working fast. A quick proof-of-concept, a few shortcuts, and suddenly you have something that looks ready. But moving vibe-coded prototypes straight into production is one of the fastest ways to sink a project. In the short term, it feels like you are saving time. In reality, you are borrowing from the future, and the interest rate on technical debt is brutal. Vibe coding is all about momentum. You write code quickly, often with AI-assisted tools or borrowed snippets, focusing on functionality over structure. It is perfect for early experiments, demos, and validating ideas.

Amortisation Explained Simply: How Your Loan Payments Are Split Between Interest and Principal When you take out a loan—whether it’s a mortgage, car loan, or personal loan—you’ll often hear the term “amortisation.” At first, it might sound like complicated financial jargon. But the idea is actually quite simple: amortisation is just the process of spreading out your loan repayments over time. Understanding amortisation is crucial because it shows you exactly how much of your monthly payment goes toward interest (the bank’s charge for lending you money) and how much reduces your principal (the actual amount you borrowed). Let’s break it down step by step. Principal: The original amount you borrow (say, \$200,000 for a home loan). Interest: The cost of borrowing, usually expressed as an a…  ( 6 min )

After my 4th semester, reality hit me like a truck: “oh crap, I need to get an internship.” I applied everywhere, gave interviews, fumbled half of them, got disappointed… and finally landed an offer. Which I refused. Out of pure confusion. Then, like the clown I was, I called them back, apologized, and somehow still got the internship. At first, I was excited. Corporate life looked shiny and glamorous in my head. I chose the Full Stack department, pumped to finally do “real dev work.” …And then reality smacked me again. The work? Mundane, boring tasks. The devs? Sitting at their desks from morning to evening like NPCs on repeat. Watching them, I thought: “Wait… is this going to be my whole life??” That’s when the depression arc kicked in. I couldn’t bring myself to work, couldn’t learn pro…  ( 6 min )

When was the last time you downloaded an app and deleted it within minutes because it crashed, froze, or simply didn’t feel reliable? You’re not alone-according to a 2023 TechRadar survey, 70% of users uninstall an app within a week if they encounter performance issues. That’s the brutal reality of the digital world: users have zero patience for buggy apps. This is exactly where mobile app test automation comes in. I still remember working on my first mobile project as a junior tester. It was a simple e-commerce app, and everything looked fine during manual testing. But once the app hit the real world—with hundreds of devices, OS versions, and unpredictable user behaviors-it fell apart. Cart errors, login glitches, and payment bugs all showed up within days. It was painful. That was my wak…  ( 8 min )

Hey friends 👋, Today I started the OverTheWire Bandit challenges — a playground where you learn real Linux + security skills by solving tiny puzzles. It felt like a game where each level teaches you one new “hacker move.” Here’s my journey from Level 0 to Level 4, explained like I’d tell a friend. At first, I had no idea what SSH was. After running man ssh, I learned: SSH (Secure Shell) lets you control another computer securely from far away. To connect to Bandit, I used: ssh -p 2220 bandit0@bandit.labs.overthewire.org # password: bandit0 This dropped me into another computer like stepping into a remote terminal. Boom 🎉, Level 0 cleared. I logged into bandit1 and ran: ls It showed a file, but its name started with a dash (-). That’s tricky, because most commands treat anything st…  ( 7 min )

Sending high-volume emails is common for large organizations. They need to reach employees, customers, or both. Some use mailing services like Mailchimp, SendGrid, or MailerLite. Others prefer to handle bulk emails in-house. If your organisation uses Microsoft 365, recent changes may affect you. Microsoft has introduced new restrictions on high-volume emails to improve security and system stability. As a result, many businesses are rethinking their email strategy. In this article, I’ll explore two Microsoft solutions for high-volume email: High Volume Email (HVE) – A built-in option within Microsoft 365. Azure Communication Services (ACS) – A cloud-based alternative for large-scale email campaigns. Let’s dive in. In April 2024 Microsoft introduced the High Volume Email (HVE) service.

If you need to back up or move your MySQL data quickly, mysqldump is the tool for the job. It exports databases, tables, or just the schema into SQL scripts that can be restored anywhere. This guide shows how to use it with common examples and must-know options. mysqldump -u admin company > company_backup.sql mysql -u admin new_company data.sql mysqldump -u admin company --no-data > schema.sql mysqldump -u admin company --tables orders products > tables.sql -routines: Includes stored procedures -events: Exports event scheduler definitions -lock-tables: Locks during dump (default for MyISAM) -single-transaction: Faster, consistent backups for InnoDB -result-file: Use instead of > for better encoding on Windows By default, mysqldump writes to standard output. To save the dump to a file, use redirection like > dump.sql or the --result-file=dump.sql option. On Windows, it’s typically found under: Yes. Use --host (or -h) to specify the remote server's address. Ensure remote access is enabled and credentials are correctly provided. You need SELECT for tables, SHOW VIEW for views, and TRIGGER for triggers. Extra privileges may be required depending on options used. mysqldump is one of the most important tools in a MySQL user's toolkit. It’s ideal for quick dumps, full backups, or schema exports. With the right flags, you can ensure fast, consistent results every time. Prefer GUI? DbVisualizer lets you export entire databases in just a few clicks—perfect for those who want power without the CLI.

Inspired by @ihssmaheel and his guide to Rust for JavaScript developers I decided to start learning this general-purpose programming language from scratch. Of course, I do know other languages, but JavaScript is the one I’m using every day at work for years. I’ll share my progress with you in this beginners-oriented series. Before proceeding, here’s what I’m going to do: I plan to follow The Rust Programming Language, but in its forked version published by the Brown University. I chose to do so, because this one is more interactive than the original version, and I think it would be better for me. It’s also recommended by the language maintainers. I followed the official instructions about how-to install Rust on UNIX-like systems, so I just entered the following command, then I pressed [Ent…  ( 8 min )

So you’ve decided it’s finally time to get serious about interview prep. No more winging it, no more hoping the recruiter skips system design questions, no more “I’ll just figure it out during the interview” (spoiler: you won’t). You start Googling resources and bam, you stumble on Hello Interview, a relatively new platform promising to help you crush technical interviews with curated guides, mock interviews, and system design practice. But here’s the real question: Is Hello Interview worth it? Or is it just another subscription you’ll add to the pile, right next to your half-finished Udemy courses and that Pluralsight trial you forgot to cancel? I’ve been around the block, coding interviews, design interviews, and the endless grind of trying to find resources that actually stick. So let’s…  ( 8 min )

The CH9143 is an UART to BLE transceiver. CH9143BLE2U name. When a Central/Master is connected it will have two characteristic (channels) one for reading (Notifications) and other for writing. The board is from WeAct: https://github.com/WeActStudio/WeActStudio.CH9143_BLE2USB2UART The chip contains two modes that can be set through Low/High levels: Master and Slave modes (BLE_MODE pin in IC). The master setting only works to pair with other CH9143 / CH9140 / CH9141 creating a point to point serial communication. If don't find any other device to pair in the first seconds after powered, it will just go into Slave mode.

So you’ve decided to stop doomscrolling and actually learn something online. Nice. You fire up Google, type in “best online courses,” and suddenly two names dominate your screen: edX vs Coursera. But here’s the real question: which one actually helps you learn something useful, and not just collect another PDF certificate you’ll forget to add on LinkedIn? I’ve tried them both (usually while over-caffeinated and under-slept), so let’s break it down. edX It feels a lot like traditional education went online. Courses are structured, professors are legit, and the branding screams “serious student vibes.” Coursera It’s more of a mix: part academic, part career-focused. Want to learn AI? You can take Andrew Ng’s legendary Machine Learning course (still a rite of passage for devs). Want a Googl…  ( 8 min )

If you’re building a new product, website, or app, choosing the right content management approach can save you a lot of time and scaling issues later. Traditional CMS platforms like WordPress work well initially but can limit flexibility as your needs grow. This is where Headless CMS comes in. What is a Headless CMS? A Headless CMS is a content management system where the backend (content storage) is separated from the frontend (your website or app). Instead of using built-in themes, you connect your CMS to frameworks like Next.js, React, or Vue.js via APIs. Benefits for Startups & Developers Flexibility: Design your frontend exactly how you want without CMS restrictions. Scalability: Your content can be reused across websites, apps, and other platforms. Faster Development: Developers can use modern frameworks and workflows. Future-Proof: Since the frontend and backend are decoupled, you can upgrade or replace one without breaking the other. Popular Headless CMS Options Here are some beginner-friendly and powerful Headless CMS platforms to explore: Sanity.io – Great for real-time collaboration and flexible APIs. Builder.io – Visual editor combined with headless CMS features. Contentful – A popular enterprise-ready CMS. When to Use Headless CMS? If your project needs custom frontend, supports multiple platforms (web + mobile), or requires high scalability, then headless CMS is a strong choice. Startups benefit because it avoids lock-in and allows teams to grow their tech stack over time. Pro Tip Pair your Headless CMS with frameworks like Next.js or Nuxt.js for smooth rendering and SEO-friendly performance. Note: If you’re a startup or developer exploring headless CMS solutions, working with an experienced web development company can make the integration process much easier. Companies like RW Infotech specialize in modern development stacks and headless CMS implementation. https://www.rwit.io/service/web-development  ( 6 min )

What is an SIEM Tool? The acronym for a security information and event management technology is SIEM. This cybersecurity solution gathers and tracks logs from all of an organization's IT systems to assist in identifying, evaluating, and responding to security threats. What it accomplishes: compiles information from servers, firewalls, endpoints, apps, cloud services, and other sources. Events that are related—looks for suspicious patterns or abnormalities in data (such as repeated unsuccessful login attempts or odd data transfers). Security teams are alerted when possible threats are identified. Aids in compliance: By keeping and examining security logs, it helps adhere to regulations such as ISO 27001, HIPAA, and PCI-DSS.

SurrealDB: shiny newcomer, low-level database, or both? SurrealDB is admittedly a pretty shiny database. It's built in Rust, a programming language that has just barely hit the 10-year mark since it hit version 1.0. A good deal of attention is paid to the website and brand design, and the official Surrealist app is not only slick but even capable of visualizing data as an interconnected net of records. This blog post goes into further detail on how this graph visualization works, leading to output like the following that lets you see which European countries belong to which intranational groups. But the other side of being a database written in a low-level language like Rust is that you can compile it to machine code with a single command and do everything you want with it on the comman…  ( 21 min )

🚀 My Journey with SQL on Oracle LiveSQL | Assignment Practice As part of my DBMS assignment, I decided to go hands-on with Oracle LiveSQL and practice real-world SQL queries. What started as just another task turned into an exciting journey of creating tables, inserting data, altering structures, and running some powerful queries. Let me walk you through my experience! 🏗 Step 1: Creating Tables I began with three main tables: Students – to store student details Courses – to hold course information Enrollments – to manage the many-to-many relationship between students and courses CREATE TABLE Students ( CREATE TABLE Courses ( CREATE TABLE Enrollments ( 📸 Screenshot proof of successful table creation: ✍️ Step 2: Altering & Inserting Data Next, I added a Phone Number column to the Students table and inserted some sample data. ALTER TABLE Students ADD (PhoneNo VARCHAR2(10)); INSERT INTO Students (StudentID, Name, Dept, DOB, Email) VALUES alice@example.com'), bob@example.com'), charlie@example.com'); 📸 Screenshot proof of inserted rows: I queried all student names in uppercase and calculated the length of their email IDs: SELECT UPPER(Name) AS StudentName, LENGTH(Email) AS EmailLength ✅ Output: STUDENTNAME EMAILLENGTH 📸 Screenshot of results: I also tried aggregate functions to calculate the average credits of courses and the total number of students: SELECT AVG(Credits) AS AvgCredits, COUNT(*) AS TotalStudents 📸 Screenshot output: 💡 Key Takeaways SQL is more powerful than it looks – even small queries give deep insights. Working with constraints (PRIMARY KEY, FOREIGN KEY, UNIQUE, CHECK) is essential for maintaining data integrity. Oracle LiveSQL is a fantastic tool for learning + testing SQL without needing local installation. 🎯 What’s Next? This was just the beginning! My next steps will include: JOIN queries to link Students and Courses. GROUP BY with HAVING for department-wise insights. Views & Stored Procedures to wrap logic neatly.

What is Pub/Sub? Publish/Subscribe (pub/sub) is a messaging pattern where publishers send messages without knowing who will consume them, and subscribers receive messages without knowing who produced them. A broker (like Kafka, RabbitMQ, SQS, Redis) usually sits in the middle to handle message delivery. This decoupling allows systems to communicate asynchronously and scale independently. Pub/Sub solves several common problems in distributed systems: Decoupling – Publishers don’t need to know subscribers. Scalability – Multiple subscribers can process messages independently. Reliability – Messages are queued until consumed (depending on broker). Flexibility – One message can be delivered to many subscribers (fanout). When Pub/Sub? Use pub/sub when: You want event-d…  ( 6 min )

But here’s the reality: as business ecosystems become more real-time and API-driven, EDI on its own often struggles to keep up. Why Traditional EDI Falls Short While EDI is reliable, it wasn’t built for the modern pace of business. Companies often face: Integration delays — onboarding new trading partners can take weeks. High costs — managing legacy VANs and middleware eats into budgets. Lack of real-time visibility — data often lags, leading to shipment errors or delayed payments. According to Gartner, 60% of organizations still rely on legacy EDI systems, but more than half plan to modernize their B2B integration stack within the next 3 years. APIs as the Next Step APIs don’t replace EDI entirely—but they enhance it. Modern B2B networks now combine EDI’s structure with API’s speed and flexibility. This hybrid approach ensures compliance while enabling real-time data exchange. Benefits include: Faster onboarding of trading partners. Instant updates on order statuses and shipments. Lower integration maintenance costs. The Rise of Cloud-Native EDI Platforms Instead of building and maintaining complex EDI infrastructure in-house, companies are turning to cloud-native EDI solutions. These platforms provide: Plug-and-play integrations. Automated validation of EDI messages. Real-time monitoring and error handling. This shift allows IT teams to focus less on firefighting and more on strategic initiatives. Platforms like ORDERFUL are helping businesses make this transition with flexible, API-first EDI solutions. Final Thought EDI isn’t dead—it’s evolving. The future of B2B integration lies in hybrid ecosystems where APIs and EDI coexist seamlessly. Companies that adapt now will be positioned to thrive in an increasingly digital supply chain.  ( 6 min )

One of the biggest myths about learning is that you need endless hours to master new skills. I’ve read over 1,500 books in the last 15 years, but nothing has accelerated my learning like using AI as a personal learning assistant. Here’s my system. 1️⃣ Summarise Smarter, Not Harder Instead of slogging through 300 pages, I use ChatGPT to: Summarise key chapters Highlight arguments and counterarguments Create mind maps 💡 Prompt: “Summarise [article/book/paper] into 5 bullet points, 2 examples, and 1 key action takeaway.” 2️⃣ Turn Notes Into Action Most people stop at highlights. I turn notes into checklists and exercises with AI. 💡 Prompt: “From these notes, create a 7-day action plan to apply the concepts in real life.” This way, learning becomes practice — not just theory. 3️⃣ Debate With AI When I don’t fully understand a topic, I argue with ChatGPT. “Act as a skeptic. Challenge my understanding of [topic] with 5 tough questions. Then help me refine my answers.” This forces deeper clarity and confidence. 4️⃣ Create Learning Systems I build structured learning plans with AI, like: Weekly reflection exercises Project-based challenges 📂 Resource: On the ReThynk AI YouTube Channel, I share live tutorials on how to design these AI-powered learning systems. 5️⃣ Teach Back What I Learn The fastest way to know if you’ve learned something? Teach it. 💡 Prompt: “Pretend you’re a 15-year-old beginner. Ask me 5 questions about [topic], and help me refine my explanations if they’re unclear.” Tools I Use Alongside AI Notion + AI → Smart knowledge management Readwise → Sync highlights from books/articles ChatGPT → Tutor, coach, and challenger ReThynk AI Templates & Frameworks → My pre-designed learning structures ReThynk AI Magazine → Curated AI & business insights (currently free on our website) Final Thought In a noisy world, the advantage doesn’t go to those who consume more — it goes to those who learn faster and apply smarter. 📌 Next Post: “5 Mistakes People Make with ChatGPT Prompts” — and how to avoid them.  ( 7 min )

Curiosity about real-world cyberattacks-like how huge botnets for DDoS attacks form-pushed me beyond the classroom. The only way to really learn was to spin up my own honeypot and watch the attackers come at me. To reach my goal, I started out with Cowrie, then later moved on to Dionaea and integrated everything with Splunk + Tailscale. The first priority was security, so I moved the SSH port into the 53,000 range and set up Tailscale VPN to give my laptop a stable IP and restrict access. I began with small Cowrie experiments, which went surprisingly smoothly aside from some networking and config hiccups. That success gave me the confidence to step up to Dionaea — a bigger challenge. Permissions became less of a roadblock thanks to what I’d learned with Cowrie, but getting Dionaea to log …  ( 6 min )

In The Mythical Man-Month, Fred Brooks famously wrote: The magic of myth and legend has come true in our time. One types the correct incantation on a keyboard, and a display screen comes to life, showing things that never were nor could be. In 1975, that was programming itself; type the right sequence of symbols and something new appeared. Today, we’re living through a new version of that magic. With large language models, you don’t even need the exact incantation. A vague prompt - a vibe - can conjure up working code. It feels like we’ve entered what I like to call The Mythical Vibe-Month: a world where AI gives us the illusion of infinite acceleration. But here’s the rub: magic without context is messy. “Vibe coding” works beautifully in demos, toy projects, and small scripts. But in pro…  ( 8 min )

The Idea Last year, I had my “degen” phase — three months where I spent almost every day staring at charts, checking token lists, watching crypto YouTubers, following KOLs, and joining Telegram communities with people all over the world. It was stressful, but exciting. The speed of memecoins is insane. News happens anywhere in the world and, before it hits a major outlet, a token is already live on Pumpfun. After trading and following these communities for a while, I realized it wasn’t for me. Still, as someone who loves internet culture, memes, and crypto in general, I kept watching the space daily, even if I wasn’t trading anymore. But one thing kept bugging me: good tools for traders were missing. The space feels rigged. KOLs, whales, and scammers have all the advantages, whil…  ( 8 min )

Technical debt isn't just a developer problem—it's a business problem with a real price tag. Let's break down what technical debt actually costs a typical 10-developer team: Developer Time Breakdown: Average developer salary: $120K Total cost (including benefits/overhead): $180K per developer Team cost: $1.8M annually Time Allocation Research Shows: 23% of developer time spent on technical debt (StripeReport 2023) 17% on debugging production issues 40% total "maintenance" vs. feature development The $180K Annual Loss: $1.8M × 40% maintenance time = $720K Minus necessary maintenance (20%) = $360K excess Conservative estimate of recoverable waste: $180K But that's just the beginning... Technical debt compounds like financial debt. Teams that don't address it see: Velocity Decay: 15% slower feature delivery year-over-year Quality Tax: 60% more production incidents Developer Churn: 40% higher turnover in teams with high tech debt Smart engineering leaders are now tracking: Technical debt velocity (issues resolved vs. introduced) Feature delivery time trends Production incident root cause analysis Traditional approaches (quarterly "tech debt sprints") fail because: They're reactive, not proactive They compete with feature work for priority They require expensive developer time Forward-thinking teams are exploring automation: Automated code quality enforcement AI-powered refactoring suggestions Continuous debt remediation How much is technical debt costing your team? Try this quick calculation: (Team Size × $180K) × (% Time on Maintenance - 20%) = Annual Tech Debt Cost Share your results in the comments—you might be surprised by the number.

Unleashing the Power of Hyperparameter Tuning: A Journey into Grid Search Imagine you're baking a cake. You have the recipe (your machine learning algorithm), but the perfect cake depends on the precise amounts of each ingredient (your hyperparameters): the oven temperature, baking time, amount of sugar, etc. Getting these just right is crucial for a delicious outcome. This, in essence, is hyperparameter tuning. And Grid Search is one powerful technique to help us find that perfect recipe. Hyperparameter tuning is the process of finding the optimal set of hyperparameters for a machine learning model to achieve the best possible performance. Hyperparameters are settings that are not learned from the data during training, unlike the model's parameters (weights and biases). They control the…  ( 9 min )

Before we deep dive, let's learn a couple of important concepts Sockets are endpoints for communication between computers over a network, enabling real-time data exchange. Unlike regular files, sockets do not store data but facilitate data transfer between machines. When Go requests a socket from the operating system (OS), the OS creates the socket and assigns a unique identifier called a file descriptor. A file descriptor is an integer handle that the Go server uses to manage and reference the socket. This mechanism allows the server to efficiently send and receive network data through OS-managed resources. Go uses goroutines, lightweight threads, to handle many client requests concurrently. The main goroutine continuously waits for incoming requests. For each new request, Go creates a new goroutine to process it independently without blocking the main one. This design ensures the server remains fast and scalable, handling multiple clients simultaneously. When no requests arrive, the main goroutine sleeps to conserve system resources and improve overall efficiency. The kernel is the core part of the operating system that manages hardware and processes. Network requests first travel through a router and then reach your computer’s Network Interface Card (NIC), like a WiFi adapter or Ethernet port. The NIC converts the wireless or wired signals into binary data and temporarily stores it in a buffer. It then sends a signal to the kernel to process this new data. The kernel copies the data into a socket buffer that the Go server listens to, and marks it ready for reading. The Go runtime wakes up the goroutine to read and process the request. The server sends the response back through the socket and NIC. The response reaches the client’s browser.  ( 6 min )

In 2025, software teams face one recurring challenge: building scalable, maintainable code that doesn’t collapse under complexity. While frameworks, languages, and paradigms evolve rapidly, one principle has remained surprisingly timeless: pure functions. Pure functions are at the core of functional programming (FP), and they’re quietly shaping the future of how developers think about code. If you’re still relying heavily on stateful, side-effect-heavy practices, it might be time to reconsider—because pure functions are no longer just “academic theory”; they’re practical, profitable, and powerful. A pure function is one that: Always returns the same output for the same input. Produces no side effects (like changing global state, modifying data outside its scope, or interacting with the ex…  ( 6 min )

Event-driven systems are powerful — but testing them can feel heavy. Spinning up a Kafka cluster, checking if specifications are met, producing test input, and reading results from topics… it adds a lot of overhead, especially in CI pipelines. What if you could test Kafka workflows without running a Kafka cluster? That’s exactly what Mokapi enables. Testing event-driven workflows usually means juggling infrastructure: Running a local or containerized Kafka broker Making sure topics and schemas match the spec Setting up test producers and consumers Verifying results at the topic level For end-to-end workflow tests, this slows you down. With Mokapi, you can skip the cluster and use a Kafka-like REST API for producing and consuming records — perfectly aligned with your AsyncAPI specs. Le…  ( 6 min )

Written by Josh Skorich and originally posted on spektion.com Working closely with both offensive security teams and on the front lines of runtime visibility at Spektion, I've seen a new approach to threat management take shape. Instead of relying on signatures or static patterns, the most effective security strategies today are grounded in real-time behavioral intelligence: insights drawn directly from how software actually runs. This isn't just another incremental improvement in detection technology. It's a paradigm shift that's exposing entirely new categories of risk and enabling proactive identification of threats that would have remained invisible under conventional approaches. Most security tools today rely on what I call "signature thinking": the assumption that threats can be iden…  ( 10 min )

Check it out, if that’s your kind of thing. In object-oriented programming (OOP), one of the most common questions developers face is how to reuse code effectively. Traditionally, inheritance has been the go-to mechanism: a class extends another, reusing its methods and properties while adding or overriding behavior. But inheritance, while powerful, comes with pitfalls—tight coupling, rigid hierarchies, and difficulty in adapting to new requirements. To address these challenges, the principle of composition over inheritance has emerged as a cleaner, more flexible alternative. Inheritance allows classes to sh…  ( 8 min )

Did you know that Netflix has over 76,000 genres to categorize its movie and tv show database? I am sure this must be as shocking to you as this was to me when I read about it first. Genres, rather micro-genres, could be as granular as “Asian_English_Mother-Son-Love_1980.” This is the level of granularity to which Netflix has segmented its product offerings, which is movies and shows. I think the success of Netflix answers this question on its own. Netflix is considered to have one of the best recommendation engines. They even hosted a competition on Kaggle and offered a prize money of USD 1 million to the team beating their recommendation algorithm. This shows the sophistication and advanced capabilities developed by the company on its platform. This recommendation tool is nothing but a s…  ( 11 min )

Data engineering can feel like a never-ending task with old-school ETL (Extract, Transform, Load) processes; lots of manual work, mistakes, and time. But what if your data pipelines could run independently, fixing issues and adapting without you lifting a finger? That’s where AI agents come in for autonomous ETL. These AI tools are game-changers, potentially cutting maintenance costs by half and making things more reliable. Companies like Netflix and Airbnb are already proving this works. Let’s break it down with real examples and consider what’s next. What Are AI Agents in Data Engineering? Think about a typical ETL setup: you pull data from databases or APIs, tweak it with tools like Apache Spark or dbt, and load it into places like Snowflake or BigQuery. AI agents make this better by us…  ( 7 min )

The limits of LLMs are clear, and the criticisms are valid. They lack true reasoning, a genuine grasp of cause and effect, and often hallucinate. This sparks the great debate in AI: can we achieve AGI simply by scaling these models to unimaginable sizes, triggering a dramatic emergence of intelligence? Or do we need fundamentally new models capable of genuine reasoning and understanding reality? Perhaps the best way to view LLMs is as the Neanderthals of the AI world. Neanderthals were not primitive brutes; they were the apex of their era. They were intelligent, adaptable, and masters of their domain. Similarly, LLMs represent the peak of our current capabilities. Yet, Neanderthals were not the final form of humanity. They were eventually succeeded by Homo Sapiens, a species with superior abstract thought and planning. In the same way, LLMs, for all their power, are not the final form of AI. They will inevitably be succeeded by new models capable of the true reasoning and abstract planning they currently lack. And just as Neanderthal DNA lives on within us, the foundational principles of LLMs will forever be part of AGI's architecture. Ultimately, LLMs are not the destination. They are the inevitable path, the absolute foundation, and the necessary ancestor on the journey to AGI. We must pass through their era to reach our own Homo Sapiens.  ( 5 min )

Every major productivity leap in software—from Rails and React to containerization—created a competitive edge for teams that adopted early. Now, AI is the next leap. The gap between developers who embrace it and those who resist it will be wider than anything we’ve seen before. ⸻ The New Baseline AI fluency is quickly becoming a baseline skill, not a “nice to have.” A senior engineer fluent with AI tools can prototype, validate, and pivot at a pace that a full team needed five years ago.

As a backend engineer, my goal isn't just to build features that work, but to make them fast and scalable. One of the most frequent performance issues I've encountered and one I see a lot of developers run into is the N+1 query problem. It's a subtle bug that can cripple an application's performance. In this post, I'll break down what this problem is, show you its real-world impact from my own experience, and walk you through the exact solution I use with Go and SQL. Let me set the scene with an example I ran into while working on an e-commerce application. I was building a feature to display a user's order history. Each order was tied to a specific product. My initial code fetched the user's 50 most recent orders. Then, to get the product name for each order, my code made another database…  ( 8 min )

Coding is not just about writing syntax and fixing bugs. For me, it’s also about storytelling — turning ideas into experiences and giving logic a narrative form. Whether it’s building a website, designing an interface, or writing content, I see coding as a creative medium just like art or writing. Coding as a Narrative Each function feels like a chapter with a defined purpose. Variables act like characters, carrying information through the story. Debugging introduces plot twists, forcing us to rethink the journey. The final program is the ending, bringing satisfaction when everything clicks. Where Storytelling Shapes Tech designing and editing on platforms like Canva, where visuals carried the story. Later, as I moved into web development, I discovered that coding too can be a powerful form of storytelling — one that combines creativity with interactivity. Why This Blend Matters Helps build user-focused experiences instead of plain functionality. Makes complex technical ideas easier to explain and teach. Brings creativity into problem-solving and design thinking. Conclusion connection. One connects machines with logic, while the other connects humans with meaning. Bringing them together is what makes digital experiences not just functional, but truly impactful.  ( 5 min )

Introduction Consensus algorithms are the backbone of distributed systems, enabling multiple nodes to agree on a single state despite failures or network issues. In technical interviews, questions about consensus algorithms like Raft or Paxos test your understanding of distributed systems’ reliability and coordination. These algorithms are critical for systems requiring strong consistency, such as distributed databases or leader election. This post explores consensus algorithms, focusing on Raft, and equips you to handle related interview questions with confidence. A consensus algorithm ensures that a group of nodes in a distributed system agrees on a single value or state, even if some nodes fail or messages are lost. This is crucial for maintaining consistency in systems like distribut…  ( 7 min )

Today I explored SQL Joins – one of the most important concepts in relational databases and also practiced with some coding problems on HackerRank. INNER JOIN → Returns only the matching rows from both tables. LEFT JOIN → Returns all rows from the left table + matched rows from the right table. RIGHT JOIN → Returns all rows from the right table + matched rows from the left table. FULL JOIN (or OUTER JOIN) → Returns all rows when there is a match in one of the tables. Among these, the most commonly used is the INNER JOIN. Let’s say we have two tables: movies movie_id movie_name 1 Ghajini 2 Singam 3 Kaakha Kaakha actors actor_id actor_name 1 Surya 2 Asin 3 Jyothika movie_actors movie_id actor_id 1 1 1 2 3 1 3 3 SELECT m.movie_name, a.actor_name FROM movies m INNER JOIN movie_actors ma ON m.movie_id = ma.movie_id INNER JOIN actors a ON ma.actor_id = a.actor_id; movie_name actor_name Ghajini Surya Ghajini Asin Kaakha Kaakha Surya Kaakha Kaakha Jyothika  ( 5 min )

Nobody believes that this universal key won’t be used against them, that it won’t be misused, or that they can keep it safe from any bad actor making a copy. But why am I telling you this? At this very moment, the European Union (of which I am generally fond) is currently proposing a universal key/backdoor/surveillance for everything we will ever send through our digital channels. Every message, every image, every file should be scanned - without our consent. Let me reiterate on my example with a universal key.

My Story with ALX When I think about my ALX journey, one word comes to mind: transformation. I still remember the first time I signed up for ALX. At that moment, my goal was clear — I wanted to become a Virtual Assistant. I was eager to learn how to support busy professionals, manage schedules, handle communications, and create order in the middle of chaos. Those months as a VA learner shaped me more than I expected. I learned how to manage my time, stay accountable, and adapt to fast-paced environments. More importantly, I learned the value of community — how asking questions, helping others, and sharing experiences made the journey lighter and more rewarding. But something interesting happened along the way. The more I interacted with the ALX community, the more I became curious about what was possible beyond Virtual Assistance. That’s when I discovered Frontend Development. At first, the thought was intimidating. Me? Writing code? It felt far from my background. But ALX has a way of pushing you to dream bigger than your fears. And so, I took the leap. Now, I am walking a new path as part of the ALX Software Engineering program. Learning frontend development has been challenging, no doubt — there are moments when the code doesn’t work, when I feel stuck, and when giving up feels easier. But each time, I remind myself of the same lessons I learned as a VA: Ask for help. Stay consistent. See failure as feedback. Trust the process. In many ways, ALX has become more than just an education platform for me. It’s a community of growth. A place where you don’t just learn skills — you learn how to reinvent yourself. Today, I proudly say: This journey is still unfolding, but I know one thing for sure: with ALX, growth never stops. ALX_SE #ALX_FE #ALXJourney #ALX_Africa #GrowthMindset  ( 6 min )

There have been years of investigation into automated systems for everything from aircraft, weapon systems and unmanned drones to automobiles. Despite the millions, if not billions, of dollars invested and claims made by some electric vehicle manufactures, the day of fully-automated (aka self-driving) cars is a long way off. I would argue that handing over the responsibility for developing the systems on which our society (our civilisation) is so reliant, is an exceptionally dangerous strategy. Far more dangerous than streets full of driver-less vehicles, yet we seem to be determined to hand over this vital responsibility, according to some big businesses.

The Most Important GPU Review of the Year (serious) Nvidia quietly rolled out the RTX 5050—destined for bargain-bin prebuilts everywhere—and gave reviewers almost zero lead time. Linus walks through 1080p and 1440p gaming tests, frame-generation and latency benchmarks, plus a healthy dose of real-world creator and AI workloads to see if this entry-level part can actually deliver.

https://youtube.com/shorts/-SzPdzoeviA Even great diagrams can’t stop a project from going off track. Without structure, they’re just boxes. Still, many people believe architecture is only about making diagrams. The truth is, architecture is a repeatable practice that aligns people and delivers results. Diagrams are just one part of the work. Skip aligning objectives or defining scope, and you risk misaligned execution. That means blown budgets, missed deadlines, and frustrated teams. I’ve seen it happen — one project had a beautiful architecture map but still failed because critical dependencies were ignored and integration broke down. QTAM changes that. It gets everyone aligned fast, defines scope clearly, and produces deliverables that guide execution — cutting waste, avoiding delays, and driving better outcomes. 👉 Start here — https://qtam.morin.io/  ( 5 min )

Building fast, responsive React applications goes beyond writing functional code but also includes ensuring it performs optimally. Users expect pages to load instantly, scroll smoothly, and respond without lag, no matter how complex the app becomes. However, as React apps grow, bundle sizes increase, components re-render unnecessarily, and heavy lists slow down performance. The good news is that React provides multiple powerful optimization techniques that keep apps snappy while maintaining clean, modern code. The first step toward faster apps starts before the browser even runs your code: the size of the bundle itself. If your JavaScript bundle is bloated, performance issues appear before your app has a chance to load. That's where bundle optimization comes in. When you run a build, too…  ( 10 min )

Absolute Zero - What is Contextual Prompting? Let's ground ourselves. At its core, Contextual Prompting is the practice of providing an AI system with comprehensive background information, situational details, and relevant parameters before you even make your specific request. It's the difference between asking "Write an email" and giving your LLM a meticulously crafted brief that details the target audience, brand voice, campaign objectives, industry context, and desired outcomes. Modern LLMs, despite their intelligence, lack the inherent implicit knowledge and contextual awareness that humans take for granted.

The Composite Pattern belongs to the Structural category of design patterns. treat individual objects and groups of objects uniformly, by organizing them into a tree like hierarchy. Think about a Company Org Chart. An Employee can be a individual contributor. A Manager is also an employee, but they can have multiple employees reporting to them. Now, when their details are needed in order to distribute festive coupons, you don’t want different logic for developers and managers. You would just want to call the same method, and the right thing should happen. This is exactly what the Composite Pattern does in code.

Hi everyone 👋 I’m a full-stack web developer exploring WebAR with react-three-fiber (R3F) and would love some advice. My first project is to create an info wall for an exhibition, where users can hover over images to see more information. Later, I’d like to expand into more WebAR projects using the same tech stack, possibly integrating a headless CMS. From my research, the AR frameworks that seem best suited for my use case are: MindAR: seems solid for image tracking and works well with web apps. But it's not easy to integrate it into R3F. XR engines: ZappAR and 8th Wall – powerful, but expensive and I’d like to stay independent. Other options: AR.js: seems outdated and largely replaced by MindAR. react-three/xr: looks great for VR/HMD (Quest, etc.), but not focused on image tracking. My goal is to combine R3F with an image-tracking AR solution. I tried react-three-mind, but it didn’t work well for my project and is quite slow. I tried to integrate MindAR by myself but It's quite tricky, so I wanted to ask if there is a better solution? 👉 Has anyone here successfully built a React + R3F + AR app with image tracking or other ideas? Any pointers on tutorials, boilerplates, or best practices for React-based WebAR applications would be hugely appreciated 🙏😊 Thanks in advance!  ( 5 min )

TL;DR Step-Back Prompting asks an LLM to abstract a problem (produce a higher-level question or list of principles) before solving it. That two-stage approach — abstraction → reasoning — often yields more reliable answers for multi-step, knowledge-intensive tasks. Use it selectively: it costs extra tokens and latency, so benchmark and combine with retrieval when necessary. LLM: a token-predicting neural model (GPT-family, Claude, etc.). Token: a chunk of text used by the model. Prompt: the input/instructions you give the model. Step-Back Prompting: generate a step-back question or principle list first, then use that as grounding for the final answer. Note: Be precise — many real-world failures come from ambiguous prompts. Step-Back reduces ambiguity by forcing a model to surface the rele…  ( 11 min )

In the midst of the COVID-19 pandemic in March 2020, Sree Krishna Seelam, a visionary social entrepreneur, launched WeDidIT Foundation, a youth-centric non-profit based in Vijayawada, India. Despite starting with just seven volunteers operating from a residence within a containment zone, WeDidIT experienced explosive growth. This remarkable progress culminated in WeDidIT being honored with the Economic Times Award for Excellence in Social Entrepreneurship in 2021—a testament to its lasting impact . WeDidIT's ethos is deeply rooted in the belief that volunteering is not just an act of service but a path to personal transformation and leadership. During the pandemic lockdown, volunteers were encouraged to feed birds or animals at home, share photos on social media, and tag friends—creating a ripple effect of simple acts of kindness . Another notable initiative involved youth interviewing senior citizens (75+) in their circles, compiling responses and videos. These intergenerational exchanges fostered empathy, wisdom, and strengthened bonds between generations . Beyond localized projects, WeDidIT aligns with the United Nations Sustainable Development Goals—addressing issues such as No Poverty, Quality Education, Gender Equality, Clean Water and Sanitation, and Climate Action, among others . The foundation’s deeper mission is to cultivate volunteers into empathetic, purpose-driven leaders who carry the spirit of service beyond any single initiative . With the rallying cry, “To leave this planet a better place than it was before we arrived,” WeDidIT extends an open invitation to individuals of all walks of life—students, professionals, artists, and activists—to join a movement rooted not in perfection, but in shared humanity and purposeful action.  ( 6 min )

My fellow contributor @ehuelsmann did the heavy lifting of yet another bug fix release of the Perl distribution: Workflow. GitHub perl-workflow release 2.06 The bugs was found by @ehuelsmann himself, as he uses Workflow in another application he is working on and as use and use-cases get expanded, bug sometimes appear, bugs that would go unnoticed if the code was not used and evaluated. That is why we cherish users and contributors and users who are also contributors, which is common in open source. @ehuelsmann is already hard a work on 2.07, more information as the release gets shipped to CPAN. Here follows the change log for the bug fix release. 2.06 2025-08-12 bug fix release, update not required Autorun triggered upon workflow creation invoking non-existent method, PR #258 Observers not notified of events triggered by autorun initial actions, issue #259 Remove duplicated POD section from YAML config module, PR #255 Missing 'autorun' value in 'completed' event, issue #257 Clarified documentation and release notes on event changes between 1.62 and 2.x, issue #257  ( 5 min )

Building effective AI products isn't just about having access to powerful language models—it's about implementing the right design patterns that bridge the gap between AI capabilities and user needs. Whether you're developing a coding assistant, content generator, or analytical tool, these seven patterns will help you create AI experiences that users actually want to use. The Restating pattern addresses one of the most common friction points in AI interactions: miscommunication. Instead of immediately executing a request, the AI explicitly states what it understood from the user's input. Why it works: LLMs excel at filling gaps and correcting imprecise human input by leveraging conversational context. By restating before acting, you eliminate confusion and prevent costly mistakes. Implemen…  ( 9 min )

If you’ve ever sat through a Sprint Planning that dragged on for hours, you know the pain. Teams get stuck in endless discussions, debates over estimates, or worse—planning the entire sprint down to the smallest detail. After facilitating 100+ Sprint Plannings as a Scrum Master, I’ve seen these mistakes over and over. And I’ve also found a few reliable ways to keep things on track. Sprint Planning isn’t about solving every problem before the sprint starts. It’s about answering three core questions: Why is this Sprint valuable? What can be done this Sprint? How will the chosen work get done? If you’re doing anything more than that, you’re probably wasting time. Here are the most common pitfalls I’ve seen: The backlog isn’t ready.

Few foods have captured the hearts (and appetites) of people around the world quite like pepperoni. Known for its smoky, spicy, and savory flavor, pepperoni has become a staple ingredient in everything from pizzas to sandwiches, pastas, and party platters. Its bold taste and versatility make it a favorite for both casual meals and gourmet creations. Pepperoni traces its roots back to Italian-American cuisine, where it was crafted as a variation of traditional cured salamis. Over the years, it has grown into one of the most recognizable and widely used toppings in modern cooking—especially as the star of countless pizzas enjoyed worldwide. Unlike many other cured meats, pepperoni strikes a unique balance between heat and richness. Its seasoning blend, typically featuring paprika, garlic, and chili, gives it a distinctive flavor profile. This makes it not only delicious on its own, but also the perfect ingredient to complement cheese, bread, pasta, and even salads. While pizza may be its most famous use, pepperoni’s versatility stretches far beyond. It can be added to breakfast omelets, folded into sandwiches, tossed into pasta dishes, or paired with cheeses on a charcuterie board. Its ability to fit into so many different meals is part of what keeps it popular across cultures and generations. Pepperoni has earned its status as a timeless classic, offering a perfect mix of spice, flavor, and convenience. Whether you’re cooking a family dinner, preparing snacks for friends, or just craving a bold bite, pepperoni is always a winning choice.  ( 6 min )

Web engagement used to revolve around the click. Companies built entire growth strategies around search traffic, SEO rankings, and paid campaigns designed to drive user action. But that model is eroding quickly. AI-native browsers like Comet and ChatGPT are changing the rules. They go beyond summarizing information. They can pull answers, move through pages, and finish tasks before the user ever has to click a link. The fundamentals of digital interaction are being rewritten. Business leaders need to respond with systems that make sense in this new environment. Delegation is Replacing Discovery The shift is already underway. Where browsing was once a manual, tab-driven process, AI browsers now handle that workload. Comet, built by Perplexity, is the most advanced version on the market. …  ( 8 min )

Functions are the beating heart of JavaScript. They let us organize code, reuse logic, and build anything from small utilities to giant frameworks. But what really makes functions flexible are their parameters. These little guys decide how our functions receive input and how dynamic they can become. In this deep dive, we’ll explore everything about parameters and arguments in JavaScript. Buckle up, because by the end, you’ll be handling function parameters like a pro magician pulling endless tricks from a hat! Let’s clear the confusion first. Parameters are the names listed in the function definition. Arguments are the actual values you pass when you call the function. function greet(name) { // 'name' is a parameter console.log("Hello, " + name); } greet("Alice"); // "Alice" is an a…  ( 8 min )

I’m taking a gap year and my goal is to get a junior back-end position. I recently completed the CodeCademy Back-end Developer Course. To find out the standards for a back-end developer, I read stories and articles and what I commonly found were: Active GitHub profile (daily commits) Well-structured and documented programs (modular & uses Swagger Docs) Projects that are specific to my skill set (back-end would be APIs, server-side logic, databases, etc.) To implement this, I've planned out my year: Weekly mini-tasks to strengthen back-end skills Midyear project which compiles skills learned A capstone project Job prep for internships/junior position This is a fairly simple plan and I would love to hear input & feedback from the community about this plan. 👉 What other standards stuck with you that helped you get the job?

In the previous lesson, we set up our Kotlin learning environment and completed our first program. This lesson will delve into the core of Kotlin's basic syntax—variables, data types, and operators. These form the foundation of any programming language, and mastering them will enable you to write functional code, laying the groundwork for learning concepts like functions and classes in subsequent lessons. Variables and constants are basic units for storing data. Kotlin makes a strict distinction between "mutability" and "immutability," which is an important difference from other languages like Python. In Kotlin, variables are declared using var and val, with the key difference being whether they can be reassigned: var (short for variable): Declares a mutable variable that can be reassign…  ( 14 min )

TL;DR: Large Language Models are powerful probabilistic predictors, but single-pass outputs can be fragile. Use Chain-of-Thought (CoT) to force step-by-step reasoning, Self-Consistency to sample many reasoning paths and vote, and Universal Self-Consistency (USC) to extend that voting to free-form outputs by letting an LLM pick the best response. Practical snippets and action cards included. Alright, let's architect some robust AI. You've got complex problems, and I've got the blueprints for turning Large Language Models (LLMs) into reliable, consistent problem-solvers.

Most consultants now use AI for content and strategy, but few apply the clarity and structure that drive results. You’ve probably seen it already. AI-generated pitch decks, polished landing pages, and neatly packaged strategy docs. What used to take hours now takes minutes. And yet, most of it feels empty. When everyone has access to the same tools and the same frameworks, more content doesn’t help. It just raises the noise level. The real difference comes from who thinks more clearly and builds systems that resonate. “Good Enough” Is the Starting Line, Not the Finish Sure, generative AI can produce decent strategy docs, clean content, and research summaries that look impressive on the surface. But this is everywhere now. Polished content is just the baseline, not a differentiator. Amy Be…  ( 7 min )

The childcare industry was valued at $60.4 billion in 2022 and continues to grow steadily. With more families where both parents work, the demand for flexible, reliable babysitting solutions has never been higher. Here are a few reasons why building a babysitter app makes sense today: Dual-income households are the norm. More parents are career-focused and willing to pay for flexible childcare options. On-demand services are booming. Just like food delivery or ride-hailing, parents want babysitters available on short notice. Trust through tech. AI matching, background checks, and secure payments make booking babysitters safer than ever. Sitters need visibility. Many caregivers only work part-time and need platforms to market their services easily. It’s more than babysitting. Pet sitting, tutoring, and even virtual babysitting are growing side-markets. Platforms like Care.com and UrbanSitter have already proven the model, but there’s still space to innovate — whether that’s in niche services, better security, or improved user experience. 👉 We’ve put together a full guide on building a babysitter app, covering features, business models, and challenges.

Theoretical Foundations of Digital Transformation Evolution of Agent-Based Systems Strategic Role of Intelligent Agents in Organizations Integration with Digital Infrastructures Human-Machine Collaboration Ethical and Governance Dimensions Impact Across Sectors The Role of Advanced Development Paradigms Future Directions of AI Agent Research Conclusion The phenomenon of digital transformation is inseparable from the evolution of intelligent computational agents. Through their capacity for autonomy, collaboration, and adaptability, agents reconfigure the structures of organizations, the design of infrastructures, and the dynamics of human-machine collaboration. The theoretical, ethical, and practical implications of this evolution reveal that agents are not merely instruments of efficiency but fundamental participants in socio-technical ecosystems. The future of digital transformation will be defined by the capacity to harness intelligent agents responsibly, integrating them into systems in ways that align with human values and institutional objectives. By advancing design paradigms such as Agentic Ai Development, Ai App Development, and Ai Development, societies can ensure that the transformative potential of intelligent agents is realized in a manner that is equitable, sustainable, and innovative. The progression of computational agents thus symbolizes more than technological advancement. It represents a redefinition of the relationship between humans and digital systems, a relationship that will continue to shape the structures of economy, governance, and culture in the era of intelligent transformation.  ( 10 min )

Nine months ago, I got laid off. During my brief spell looking for a job (before deciding to go indie), as I have always been, I wanted to do it in an organized manner. I used to rely on Airtable base for collecting all the job postings I found online, to then take notes and track activities and so on, but this time decided to look for a ready-made solution. Found some cool products but they are too expensive for my liking, costing between $20-40 a month! That is how the idea of HuntingPad was born and the core feature seemed simple: clip job posts with one click from anywhere in the browser! Spoiler of what I ended up achieving What I didn't expect was that this "simple" feature would lead me through a maze of technical decisions - from expensive webscraping APIs to LLM token optimizati…  ( 10 min )

Brahma-JS: Ultra-Low Latency JS Runtime Powered by Rust Rust is amazing for speed, safety, and stability—but let’s be real: most JS/TS devs don’t want to wrangle the borrow checker, strict type system, and ownership rules just to build web APIs. That’s why I built Brahma-JS — an ultra-low latency runtime written in Rust on top of Tokio + Hyper, but plug-and-play with Node, Deno, and Bun. All heavy lifting (req.body, headers, query parsing, etc.) runs in Rust. Works directly inside your existing JS ecosystem (Node, Deno, Bun). Fire-and-forget, fully sync-style architecture. Lets you write type-safe, memory-safe, blazing-fast HTTP routes with the simplicity of JS. npm i brahma-firelight const { useBrahma, startServer, redirect } = require("brahma-firelight"); useBrahma((req) => { if (req.path === "/hi") { return { headers: { "Content-Type": "application/json" }, status: 200, body: JSON.stringify({ message: "Hello World from Brahma-JS!" }), }; } if (req.path === "/bye") { return redirect("https://example.com"); } return { status: 404, body: "Route not found", }; }); const port = process.env.PORT || 3000; const host = process.env.HOST || "0.0.0.0"; startServer(host, +port).then(() => { console.log(`🌀 Brahma-JS server running at http://${host}:${port}`); }); On a tiny AWS EC2 t2.micro, I hit: 33.2k req/s within 10s of load testing No proxy, no hacks — just raw Rust (Hyper + Tokio) under the hood Benchmarks August 2025 (That’s significantly faster than Express/Fastify on the same hardware.) 👉 GitHub: Shyam20001/rsjs Star ⭐ the repo if this excites you PRs welcome for early testers Drop issues with the features you’d want next Nobody needs to give up their ecosystem anymore.

"Faces don’t lie — but landmarks sometimes do." Hey there! In this post, I’ll share my journey of building a Face Landmark Detection pipeline using OpenCV DNN and Facemark LBF. The system takes a raw video as input, detects faces, extracts 68 facial landmarks, smooths them across frames, and finally outputs: an annotated video with landmarks and bounding boxes an optional CSV file with landmark coordinates for every frame The idea was simple: "Take a face → get the points." But to make it robust, I had to mix deep learning detection with classical landmarking and add a touch of signal processing. The project is split into modular components: detector.py → Loads and runs the DNN-based face detector (SSD ResNet) landmarks.py → Drawing utilities for the 68-point facial structure helpers.py → …  ( 6 min )

How AI Can Keep Documentation Alive There's an uncomfortable truth in our industry: project documentation is almost always outdated. And there are only two basic rules to avoid it: Write it. Keep it updated. We all stumble on the second one. In this post, I won't talk about how to write good documentation (that's an art on its own), but about how to force it to stay in sync with code—automatically. Documentation is both a blessing and a curse for every dev team. It's essential for maintainability and collaboration, but it's always one step behind the code. For years, as a Tech Lead, I tried everything: gamification, extra story points, strict PR reviews. Result? It never really stuck. I gave up. This chronic problem has now turned into a paradox.

Week 3 — Shop & Product Detail pages Over the third week of building Treazurex I focused on the product-facing pages: the Shop page and the Product Details page. These are the two screens most users interact with, so getting layout, information hierarchy and interactions right was my main priority. What I did Built the Shop listing: product cards, basic filters, and the grid/list layout. Implemented the Product Details page: images, descriptions, price, and buy/add-to-wishlist actions. Fixed several small bugs that appeared while connecting the pages (routing edge-cases, broken links, and a couple of state bugs). What took the most time Design & polish. Making the pages look professional and feel cohesive took more time than the core functionality. I spent a fair amount of time exploring …  ( 7 min )

1. What is a Schema? In PostgreSQL, a schema is just a folder inside your database where you keep your tables, views, and other objects. You can even have the same table name in different schemas. It’s best to name it after your app so it’s easy to keep things organized. In our case, we’ll create a schema called school. Example in SQL: CREATE SCHEMA school; In DbSchema tool, you can create it following these steps: 1. Start a new schema from scratch in the "Welcome Screen". 2. Select the PostgreSQL database and name the project (model) as you wish. 3. Right-click in the database tree → Create → Schema → give it a name, like school, in our case. When you design visually a ER diagram: You see all the tables and how they connect Which columns are keys or have constraints You can drag to c…  ( 8 min )

Introduction When I first started exploring AWS, I quickly realized that reading docs and watching tutorials wasn't enough for me. I wanted to get my hands dirty with real projects. The problem was that most resources either covered concepts without context or jumped straight into production level setups without explaining the "why." After some searching, I came across a course called AWS Mastery: 26 AWS Cloud Projects for Engineers & Architect on Udemy by Pravin Mishra. What I love about this course is that it isn't just theory, it focuses on practical, project-based learning. So I've decided to take on a personal challenge of working through each project without looking at the solutions while documenting my process here in this little world of mine. This way, I can build confidence whi…  ( 10 min )

Starting something new is always exciting—and a bit daunting! As a developer with experience in React and FastAPI, I recently decided to dive into the world of databases by learning SQL using PostgreSQL. My main goal is to bridge the gap in my backend skills and better understand how databases power the applications we build. With its open-source nature, strong community, and powerful features, PostgreSQL is a natural fit for those looking to expand their backend capabilities. It’s widely used in both small projects and large-scale production systems, making the skills transferable and future-proof. So far, I’ve covered the fundamentals: Installing PostgreSQL on my machine and setting up my first database Learning and practicing essential SQL commands like: CREATE TABLE INSERT SELECT Wri…  ( 6 min )

Large Language Models like GPT LLaMA, and Claude have seen a surge in popularity in the business world over the past few years. These advanced AI models process and produce text in ways that feel human, which makes them useful in a lot of business areas. Businesses are using LLM to automate customer support or to manage internal knowledge in a perfect way. But, when they rely on outdated LLM then they may face various issues like for more complex business demands, they may not give you proper results. That’s why, many businesses feel that they should update their LLMs to meet their business goals. When you make changes or adjust LLMs then it will affect their overall performance like how accurate they are, and how well they align with your business goals.

If you run last-mile in an apartment-dense metro, you’ve lived the pain: missed first attempts, drivers circling for parking, and rescue routes blowing up OT. The fix isn’t just “better maps.” It’s the boring, vital plumbing inside a route optimization app, clean geocodes, precise apartment waypoints, and an ETA model that reflects reality at curbside, not on a highway. This post breaks down how those pieces fit, and what operators should ask vendors before the next peak. At the core is geocoding. It turns an address into a latitude/longitude the router can trust. The difference between rooftop and centroid placement is the difference between a first-attempt POD and a second attempt tomorrow. For single-family stops, a centroid might be “close enough.” For towers and gated complexes, it’s…  ( 8 min )

In Silicon Valley's echo chambers, artificial intelligence has supposedly conquered coding. GitHub Copilot autocompletes your functions, ChatGPT debugs your algorithms, and Claude writes entire applications from scratch. Yet beneath the marketing fanfare and venture capital euphoria lies an uncomfortable truth: human programmers remain irreplaceable. While AI coding assistants excel at mundane tasks and pattern matching, they fundamentally lack the creative problem-solving, contextual understanding, and architectural thinking that define exceptional software development. The statistics surrounding AI coding tools paint an impressive picture. Microsoft reported that GitHub Copilot users complete tasks 55% faster than their unassisted counterparts—a figure that has become the rallying cry fo…  ( 19 min )

Most developers have seen this pattern before. At first, the team picks up tools like Zapier, Make, or HubSpot to move faster. They solve a few problems quickly, but then… everything gets messy. Data duplicated across CRMs, spreadsheets, and APIs. Integrations failing silently, forcing someone to “just fix it.” Compliance gaps that SaaS vendors won’t cover. Scaling limits where the workflow just can’t keep up. This is what we call the SaaS plateau. Off-the-shelf tools stop being accelerators and start becoming blockers. When you’re stuck patching integrations or debugging brittle APIs, it’s a signal. The problem isn’t you — it’s the architecture. A custom AI system changes the game: Single source of truth → no more wondering which system has the right data. Code-first integrations…  ( 7 min )

It’s 2025. Immunefi and HackenProof might serve Web3 clients, but for us — the developers — the flow is still Web2. We’re long overdue to fix this. It’s time for something we own. ⚡ Introducing: The Developers Protocol This is our protocol. Just proof, payout, and progress. We call it: A zk-native, on-chain bounty system built by devs, for devs. 🧠 Why This Matters The current systems still gate the most important part of the process: us. We have to ask to submit. We have to wait to get paid. We often get deplatformed or ignored — even after saving entire protocols. Meanwhile, proof-of-exploit sits on our disk, ready. We can build that. Today. 🔄 Our Great Irony: We Forgot Ourselves Here’s the real kicker: We’ve designed zk-voting. But we forgot to fix the most critical PoC of all: our own. This is our own unsolved exploit. 🔧 What It Looks Like ✅ Submit a proof (zk-SNARK, signed hash, or PoC artifact) This is: Proof-of-Exploit Proof-of-Impact Proof-of-Authorship Proof-of-Code 🧑‍💻 And We’re the Right People To Build It It shouldn’t take long: zk circuits — we’ve done harder Solidity vaults — minimal Submission CLI — weekend job Decentralized bounty registry — a few commits away We are not just the security layer. And it’s time we start acting like it. 📣 Call to Arms If you’re a dev, this is your bounty call. 💥 Solidity / zk-devs — comment below Let’s get this spec on GitHub. 🏁 One Last Reminder: We forgot to secure ourselves. 💬 Comments Section Suggestions (For DEV.to engagement prompts at the bottom) “Would you use this instead of HackenProof/Immunefi?” “What zk format should we use for the first verifier?” “What’s the biggest flaw we must defend against in v1?” This is the one we’ve been waiting for.

Over the past few weeks, I’ve been experimenting with building a car classified script — something like a small-scale version of Autotrader or Cars.com, but with a focus on simplicity and adaptability. • Car Listings with Deep Filters • Backend: PHP + Codeignitor (for modularity) Search Speed on Large Data Filtering by make, model, location, and price killed performance after ~50k entries. Index tuning + caching helped, but I feel there’s a smarter approach. Image Uploads & Compression Car sellers love uploading 10+ high-res images. Handling auto-resize + CDN storage without killing speed was tricky. Dynamic Taxonomies Brands, Models, Variants, Years — keeping this flexible but not overly complex was harder than real estate listings. Payments for Featured Ads Simple integration with Stripe/PayPal works, but what’s the best way to keep it modular for regional gateways (PayU, Razorpay, etc.)? • How would you handle fast search + filtering at scale (Elasticsearch? Algolia? Something else?) I’m experimenting with a mobile app integration where listings update in real-time between the web + app. Also exploring a plugin system so small dealers can white-label their own version. Would love to hear from others who’ve tackled classified or marketplace apps: • What dev shortcuts saved you time? • What mistakes should I avoid scaling this?  ( 6 min )

If you’ve been building modern apps with React, Next.js, Angular, or Vue, chances are you’ve run into messy APIs, performance bottlenecks, or “too much data vs too little data” problems. That’s where Backend for Frontend (BFF) comes in. This article will explain what BFF is, why we need it, when to use it, real-world scenarios, common pitfalls, and examples — in the simplest way possible. Imagine you’re building an e-commerce app. Your mobile app needs a very compact API response (just product name, price, image). Your web app needs a detailed product view (reviews, specs, seller info). Your admin dashboard needs extra APIs (stock, margins, supplier details). If all of them talk directly to your core backend (say a bunch of microservices), you’ll end up with: Over-fetching data (getting mo…  ( 8 min )

If you’ve ever troubleshooted a slow internet connection, you’ve probably typed: ping google.com and watched those little reply times scroll by. It feels like a digital knock on someone’s door: “Hello? Are you there?” But here’s the twist, unlike most network tools, ping doesn’t use any port at all. When we think of network communication, ports are everywhere. Websites? They use TCP port 80(HTTP) or 443 (HTTPS). SSH? That’s usually port 22. DNS lookups? UDP port 53. But ping is different. It doesn’t ride on TCP or UDP, where ports live. Instead, it uses a separate protocol: ICMP (Internet Control Message Protocol). ICMP works one step lower in the networking stack — at the network layer (Layer 3) instead of the transport layer (Layer 4). And since ports only exist in Layer 4, ping never t…  ( 7 min )

Are you someone who works shifts and has trouble sleeping? Shift work sleep disorder is a common problem for people who work unusual hours, and it can make it hard to get enough rest at night. When your work hours keep changing, it can mess up your body's natural rhythm for sleep, which can leave you feeling sleepy or anxious during the day. So, what can you do to help with this problem and get the rest you need? Here are some tips to help you manage shift work sleep disorder and improve your sleep: Even if your work hours change, make an effort to have the same bedtime and wake-up time each day. Aim for at least 7 to 9 hours of sleep. This helps your body's internal clock stay on track and improves your sleep. Keep your bedroom dark, cool, and quiet. Use blackout curtains, a white noise machine, or earplugs to block out any distractions that might keep you from sleeping. If you still have trouble falling or staying asleep, you might want to try some Natural Sleep Supplements. Look for ones that have ingredients like melatonin, valerian root, or magnesium, which can help your body get ready for sleep. Avoid drinking coffee or eating big meals close to bedtime. Limit time spent on screens before sleep, and try relaxing activities like meditation or deep breathing to help you feel more calm and ready for rest. If you've tried these steps and are still struggling with sleep, it might be a good idea to see a doctor or sleep specialist. They can give you more personalized advice or suggest other treatments that could help. By following these tips, you can better manage shift work sleep disorder and feel more rested. It's important to take care of your sleep because it affects your energy, mood, and overall health. Don't wait too long to take steps that can help you feel better.  ( 6 min )

Agile terminology is something almost every team member comes across—whether in daily stand-ups, planning sessions, or project updates. Words like sprint, backlog, and retrospective have become part of everyday conversations. But here’s the thing: Agile terminology doesn’t stay the same. Just like the way teams work changes, so does the language they use. In 2025 and heading into 2026, we’re starting to see new terms appear in Agile conversations. Some of them stem from the rise of AI in Project Management, while others result from the shift toward focusing on outcomes rather than just outputs.

Every developer has been there. You're staring at a 300-line function that somehow grew into a digital tumor over six months of "quick fixes." The code works, but it's unmaintainable. You know you need to refactor it, but the fear creeps in: what if you break something? What if the AI suggestion misses critical business logic? What if you lose control of your own codebase? I've found a way to use AI for refactoring that doesn't turn me into a passenger in my own code. It's not about blindly accepting AI suggestions or rejecting them entirely. It's about creating a partnership where I maintain architectural control while leveraging AI's pattern recognition abilities. Most developers approach AI refactoring like they're ordering from a drive-through menu. They paste their messy function into…  ( 9 min )

If you’ve enjoyed our last couple of tips about CouchDB document design then you’ll appreciate a tip that helps you query CouchDB quickly. This advice is relevant for all query mechanisms in CouchDB: Views, Mango Queries, and even Search. All query mechanisms in CouchDB use design docs to define which fields to use when querying your document. We call this the query definition. They look different for each of the mechanisms, but their function is the same in each case. When changing the query definition of a design document, CouchDB will re-index all documents in your database before it can respond to any queries for them. If you have a lot of documents in your database, going through all documents for re-indexing can take a while, minutes, hours, sometimes days. During application develop…  ( 6 min )

Expose your wepapp with localtunnel Ever needed to show a local app to a teammate, a webhook, or a QA engineer who “doesn’t run things locally”? Enter localtunnel: the zero-config way to publish your localhost to the internet with a sharable URL. It’s like handing your app a passport and telling it to go see the world—safely, temporarily, and without DNS rituals. Below is a quick guide with a tiny Node.js + Express “Hello, world!” and how to expose it using the localtunnel library. localtunnel creates a secure tunnel from a public URL to a port on your machine. You run your app on, say, localhost:3000, and localtunnel gives you a URL like https://curly-pigs-play.loca.lt that forwards traffic to your local server.

Problems Solved: #125 Valid Palindrome #15 3Sum This continues my daily series (Day 5: String + Two Pointers + Sorting). Today is a special day 🎉 — I’ve officially hit my 5‑day streak of solving and documenting problems. My goal is to keep this streak going consistently and build strong problem‑solving momentum. Today’s focus was on two classic patterns: String cleaning + two‑pointer palindrome check (ignoring non‑alphanumeric characters). Sorting + two‑pointer pair search inside a triple loop for 3Sum. Practiced careful duplicate skipping logic to avoid redundant answers. Saw how the same two‑pointer pattern can apply to very different problem types (string vs. array sum). class Solution: def isPalindrome(self, s: str) -> bool: s = ''.join(c.lower() for c in s if c.isalnum…  ( 7 min )

“What got you here won’t get you there.” That saying holds true in software development more than anywhere else. Imagine this: You’ve built a solid back-end system that works perfectly for your startup’s first 1,000 users. Everything is smooth… until suddenly you hit 10,000 users, then 100,000. Suddenly, performance drops, errors multiply, and adding new features feels like trying to fix an airplane mid-flight. This is the story of countless developers and companies who start with a monolithic architecture—and eventually discover the need for something more flexible, more scalable, and more maintainable. Enter Microservices Architecture. What Are Microservices, Really? In simple terms, microservices break down an application into smaller, independent services that communicate with each oth…  ( 7 min )

Code is not just for machines — it’s for people. Future-you (or your teammates) will have to read, understand, and modify your code. That’s why clean code matters. It makes projects easier to maintain, scale, and debug. Here are 10 essential clean code principles to level up your development skills: Variables, functions, and classes should describe what they do. # Bad x = 10 def doStuff(): ... # Good max_retries = 10 def calculate_discount(): ... A function should do one thing, and do it well. Don’t scatter mysterious numbers/strings in code. Use constants instead: // Bad if (status === 404) { ... } // Good const NOT_FOUND = 404; if (status === NOT_FOUND) { ... } Use a consistent style guide. Python → Black / PEP8 JavaScript → Prettier / ESLint Formatting tools remove debates and keep code uniform. Why, Not What 💬 Your code should explain what is happening. Comments should explain why: # Bad i += 1 # increment i by 1 # Good i += 1 # move to the next index for processing If you copy-paste code, that’s a red flag. Extract it into a function or utility. Handle errors early and clearly. Don’t let issues hide deep in your program. Tests = clean code’s safety net. They ensure changes don’t break existing functionality. Avoid over-engineering. If your solution is complicated, ask: “Is there a simpler way?” Code ages. As requirements change, revisit and clean it up. Small, frequent refactors are better than giant rewrites. Clean code isn’t just about style — it’s about maintainability, readability, and professionalism. The cleaner your code, the easier it is for others (and your future self) to work with it. 💬 Which clean code principle do you struggle with the most? Or do you have your own golden rule? Share it in the comments 👇  ( 6 min )

(Automated) testing is probably one of the most overlooked technique in the programming world. Traditionally in the software development industry we had a clear separation between "programmers" or "coders" or "software engineers" on one hand and "qa people" or "testers" on the other hand. The latter would do the manual testing, the Quality Assurance of the product. Traditionally the company and thus the programmers relied on the QA people to find the bugs and to ensure high quality. This approach was never really good, but today it totally breaks down for a variety of reasons in a number of cases. While the application growth and has more and more complex feature the time and manpower allocated for manual QA stays constant or growth at a much slower pace. As the gap between complexity of t…  ( 7 min )

Introduction When you install software on Linux, you don’t always download it from a website like on Windows or macOS. Instead, Linux uses package managers. RPM and YUM. They work together but solve different problems. RPM (Red Hat Package Manager) is the low-level tool for handling software packages. A package is usually a .rpm file that contains the software and metadata about it (version, dependencies, etc.). RPM can install, remove, or query a package directly. rpm -ivh mypackage.rpm # installs a package rpm -e mypackage # removes a package ⚠️ Problem: RPM does not automatically resolve dependencies. If software A needs software B, you must install B yourself. YUM (Yellowdog Updater, Modified) is a higher-level tool that builds on RPM. It automatically resolves dependencie…  ( 6 min )

Hello again to all the people who are still here! For this week, on my 2nd game/mini project, I created the usual stuff, game.cpp, .h, main.cpp and added the ability to close the window with the toolbar and the escape button which I'll always think is a neat touch I also learned to create a player class! It was a bit complicated to integrate it but in the end I could get it to work and could see my player in the game window when I ran the app! I'm so excited for what's next, I hope I could get to do more though as I haven't been doing well these past a couple of weeks Anyhow, stay safe and see you all again soon! Maybe even sooner than you might think cause one week goes by really fast I'm always surprised.  ( 5 min )

Introduction "The Art of Programming is the Art of Organizing Complexity" - Edsger Dijkstra I'm not a dogma guy, so don't expect me to talk about "ports and adapters" or "clean architecture" here. Instead, I want to share a mindset that has helped me and many others build better software. What follows is not just about software, but about how to think like a great developer. Let's picture the following: you hand a group of developers a huge pile of LEGO bricks and ask them to build a rocket. Some will sketch blueprints, carefully laying out every component before placing a single brick. Others will immediately start building, creating elaborate structures, only to watch them collapse under their own complexity. But a rare few - the best developers I've worked with - will do something dif…  ( 9 min )

Understanding the Core Technologies When building AI agents, you'll face a critical decision: should you use Model Context Protocol (MCP) or traditional APIs? This choice can dramatically impact your agent's capabilities, performance, and development timeline. MCP serves as a universal translator between AI systems and external services. It creates a natural language bridge that enables LLMs to independently discover and utilize tools based on the situation at hand. The key advantage? Autonomous discovery and usage without explicit programming. Meanwhile, traditional APIs (REST, GraphQL, etc.) continue to serve as the foundation of software integration. When building with APIs, you're essentially pre-determining what your agent can do at design time through hard-coded calls or function i…  ( 12 min )

Additionally, the Makefile contains misconfigurations. Since emsdk silently ignores unsupported compilation options during build, these errors don't halt compilation. This article will…  ( 8 min )

Hey everyone – I'm a dev who got hit hard by subscription fatigue. You know the feeling: every cool AI tool wants a monthly fee, and before you know it, you're juggling a dozen paid plans. I reached a point where I thought, there has to be a free, open-source way to do this stuff. Good news – there usually is! Open-source AI tools are not just about saving money; they give you control over your data, the ability to self-host, and often a whole community adding new features. In this post, I'll share seven open-source tools that have replaced big chunks of my paid stack.

Graphics programming in Linux during the 1990s was fragmented, with developers forced to choose between virtual consoles, svgalib, and the X Window System. Each subsystem came with its own interfaces, constraints, and quirks. This created challenges for developers who wanted to write applications that worked reliably across different environments. The General Graphics Interface (GGI) project was introduced to address these challenges by offering a more portable and secure approach to graphics handling. The project’s vision centered on portability through a flexible API that could reduce complexity for developers. By simplifying API integration across backends and platforms, GGI aimed to eliminate the need for redundant code in graphics applications while also making them easier to adapt an…  ( 7 min )

1. What is Algorithm Complexity? Algorithm = step-by-step procedure to solve a problem. Complexity = how much time or memory it needs as input size grows. We measure this using Big-O notation. 2. Why Big-O Notation? It describes the growth rate, not the exact time. Helps compare algorithms (fast vs slow) independent of hardware. Example: One algorithm takes 1 second for 1000 inputs, another takes 10 seconds — Big-O tells us how this scales when inputs grow to 1 million. 🔹 O(1) → Constant time Same time, no matter the input size. Example: access arr[5], simple formula like n(n+1)/2. 🔹 O(log n) → Logarithmic time Input size shrinks in half each step. Example: Binary Search in a sorted array. 🔹 O(n) → Linear time One loop over all n items. Example: Find the max element in an array. 🔹 O(n log n) → Linearithmic time Appears in efficient sorting algorithms. Example: Merge Sort, Quick Sort. 🔹 O(n²) → Quadratic time Double loop → compare all pairs. Example: Bubble Sort, checking all pairs in a matrix. 🔹 O(2ⁿ) → Exponential time Doubles work for each extra input. Example: Recursive Fibonacci, brute force subsets. 🔹 O(n!) → Factorial time Explodes very fast → all permutations. Example: Traveling Salesman (brute force). Formula: Already solved shortcut, runs in O(1). Example: Sum of first n numbers = n(n+1)/2. Algorithm: Step-by-step method to compute the answer. Example: Loop through numbers and add one by one = O(n). ✅ TL;DR: Big-O tells us how fast/slow an algorithm grows with input size. Formulas are direct (O(1)), algorithms can vary (O(n), O(n log n), etc). Choosing the right algorithm = huge performance difference in real-world apps.

It’s not always a provider issue. In most cases, it comes down to how Linux allocates resources and how system tools report them. Here’s why: Memory: The kernel + firmware reserve a slice.

Ankita, CFO of a growing EdTech startup, stares at her screen showing 1,847 bank transactions. Her team needs to match each one to a student account. Some paid via NEFT with cryptic references like "FEES" or just their child's nickname. Others used IMPS with transaction IDs that don't match any invoice. "We're an education company," she tells her CEO during yet another late-night reconciliation session. "But I spend 60% of my time being a detective, matching payments to students."

When people hear that I worked on distributed storage at Meta, they assume I must have taken the intensely technical path: writing C++ from day one, digging deep into operating systems, and building algorithms from scratch in college. JavaScript? Web development is one of the best places to start your career as a software engineer, even if your goal is to work on systems. I didn't fully understand memory models or system calls when I started programming. But I did understand one thing: I wanted to build something real. Even building a login form introduces you to concepts like authentication, state management, HTTP protocols, layered architecture, and interfacing with databases. These are not minor ideas - they're foundational. I promise, you'll be far better prepared than someone who tries to start at the deepest end of the pool and is overwhelmed by abstraction. Every complex system you admire has started somewhere small. Google started with a basic search box. Facebook started as a student directory. Even the most advanced distributed systems begin as simple requests, moving through a stack of layers, each doing its job. Start with web development. Not because it's easy. But because it's one of the most effective ways to learn how computers work, and how people use them. And if you stick with it, you'll be surprised at how far it takes you. I certainly was.  ( 8 min )

Background – How I Landed the Task When I first joined Ozone, one of my first assignments was migrating node services to Supervisord. Soon after that, my CTO dropped a bigger challenge on my plate—something more open-ended: "Why don't you build us a tool to validate the configs we generate?" Now, here’s the tricky part—each client has their own environment, which means their generated configuration files look different. Manually validating them is not very practical. What worked for one client would completely break for another. That’s when we needed custom tooling, tailored for this validation. And before we dive in—don’t worry, this isn’t going to be a deep dive into technical jargon. My goal here is to share the approach I took to build it, the thinking process, and a few lessons (and…  ( 7 min )

It feels so great when you buy a shirt, and while paying you find out another one is free. We all love free stuff, don’t we? Now, when you’re just starting to build your website, do you really want to pay for hosting before you’ve even earned a single dollar from it? I know even wealthy people like you wouldn’t say no to free hosting 😂. Luckily, there are several cloud platforms with free tiers. One of the best is Netlify. Netlify is a platform to build, deploy, and manage modern web apps—and yes, you can deploy your React app there without paying a dime. In this tutorial, I’ll show you how to do it. Don’t worry, I won’t be customizing the React app—we’ll stick with the boring default landing page. Why? Because I’m lazy 😪. Steps: Open your workspace in Visual Studio Code. Open the terminal and create a new React App, using the command npx create-react-app app-name. Go to your app folder and run the command npm start. React's default landing page should show up at http://localhost:3000. Push your code to GitHub. Login to Netlify using Github account. Enter Signup Questions. From the List of Git providers select GitHub. Select and authorise Netlify to access your repository. Start deploying your React project. Below command is used to build your project Once your build is successful your website will be published. If you haven't given any name to your website Netlify will generate a random name. You can click on the link and open your website. You can change the name of your website by navigating to Project Configuration-> Change Project Name. Now click on your website link and share your website. Boom! Your React app is online. And you didn’t even have to touch a server, configure domains, or sell your kidney for hosting fees. Netlify did all the heavy lifting while you sat back lazy (respect ✌️).  ( 6 min )

An enumerated field has only several values. The format of filtering condition specified on an enumerated field (f) can be f =v1 or f=v2 or…, f !=v1 and f !=v2 and…, in or not in. The database compares f with n values. When the data table is large, there is a great number of comparisons, resulting in low performance. The larger the value of n, the lower the performance. If no comparisons are involved for performing the filtering operation, the performance will become much higher. esProc SPL offers alignment sequence mechanism to achieve that target.

When you submit a PR, it includes a wrong previous commit. How to remove these commits? If you are developing on another branch, switch to that branch. If you are developing on main, you can skip this step. git checkout your-branch In Github, view the current PR and check how many commits it includes. Replace n in the following command with the number of commits and execute it (if you have synchronized the fork, there will be new commits in Github, but they will not be shown in VS Code, so the rebase result may be earlier than the first commit of the PR): git rebase -i HEAD~n In the command line, you will see something like the following text: pick 888a17a add pnpm setting in windows (#15) pick 472jkda add pnpm setting in windows pick 472bd9c add switch butoon pick 0369726 add dark theme change …… The commit with the Github PR number will be shown with a hash symbol and the PR number. For example, if I want to remove the second commit, I will change pick to drop. To force push the changes, use the following command: git push origin HEAD:your-branch --force This will force push the changes to Github, and the PR commits will be updated.  ( 5 min )

“One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man.” — Elbert Hubbard Global Scopes are Essential: They provide automatic tenant filtering at the model level, preventing data leakage even if developers forget manual filtering. Multiple Resolution Methods: Support subdomain, custom domain, and path-based tenant resolution for flexibility.

In 2025, the startup game is different. The tools, architectures, and processes that once gave early adopters a small advantage are now the deciding factors between leading the market or falling behind. Founders who embrace them can ship faster, scale smoother, and win funding more easily. Those who don’t risk slower launches, higher costs, and investor hesitation. Across B2B SaaS, FinTech, HealthTech, Energy, and tech-enabled services, the pressures are the same: teams are lean, capital is tight, and user expectations are higher than ever. McKinsey reports that early adopters of modern practices can double revenue growth. Gartner says AI-assisted coding and CI/CD can cut time-to-market by 55 percent. PwC finds automation and cloud-native approaches can reduce operational expenses by up to…  ( 7 min )

API versioning is the method of managing different versions of an API over time. As APIs evolve, new features are added, existing structures are modified, or removed. This can cause applications that use the API to break. API versioning allows us to make these changes in a controlled way, ensuring that existing users can continue to work without being affected. Why is it Important? 🚀 Maintains backward compatibility 🚀 Allows new versions to be released without affecting users of older versions 🚀 Enables large changes to be rolled out step by step 🚀 Lets API consumers choose which version they want to use 🚀 Simplifies the development and maintenance process 🚀 Provides the ability to fix bugs or shortcomings in new versions ✅ In short, API versioning ensures that an API remains safe, compatible, and sustainable for both developers and users.  ( 5 min )

Java interviews often include tricky questions—not to confuse you, but to test how deeply you understand the language. The good news? With the right analogies, even the toughest questions become easier to remember and explain. 🔹 Question 1: Can We Override a static Method? ❌ No, static methods cannot be overridden (they belong to the class, not the object). Analogy: 🔹 Question 2: Why is String Immutable in Java? Answer: For security, caching, and performance reasons. Analogy: 🔹 Question 3: What Happens If You Don’t Override hashCode() and equals()? If you put objects in a HashSet or HashMap, unexpected behavior occurs—duplicates may not be recognized. Analogy: 🔹 Question 4: Difference Between == and .equals() == → Checks reference (are they the same object in memory?). .equals() → Checks value/content. Analogy: 🔹 More Tricky Questions What’s the difference between final, finally, and finalize()? Can a constructor be abstract? How does class loading work in Java? 🔹 Full List of Tricky Questions with Analogies I’ve prepared a complete guide with real-world analogies that make tricky Java interview questions easy to master 👉 🔹 Final Thoughts Tricky questions aren’t about “catching you off guard.” They’re about checking if you can explain concepts clearly and logically. Next time you’re asked one, use a simple analogy—it’ll impress the interviewer far more than a textbook definition. ✍️ Originally published via AnalogyAndMe.com  ( 6 min )

Have you ever scrolled through Twitter/LinkedIn and seen indie hackers bragging about their SaaS hitting $10k MRR and thought: “That’s cool, but I’m not building the next Stripe. So why should I bother?” Here’s the thing: building even a tiny SaaS app — whether it makes $1 or $0 — can teach you skills that tutorials and side projects simply can’t. In this post, we’ll explore why developers should build mini SaaS projects, what you’ll learn, and how to get started (without burning out). Most dev projects are to-do apps or clones. Nothing wrong with that, but they usually stop at: CRUD operations Local testing Maybe a login screen A SaaS project forces you to think bigger, because you’ll need things like: Authentication & security → handling real user accounts Payments & sub…  ( 7 min )

🏗️ Java System Design With Code: Building Scalable Systems Made Simple When interviewers ask you system design questions in Java, they’re not just testing syntax—they want to know if you can think like an architect. But don’t worry: with the right patterns, examples, and mindset, system design in Java becomes much less intimidating. 🔹 Why System Design Matters Companies like Amazon, Google, and Netflix want developers who can design systems that scale. Writing code is one thing—but designing how components interact is the real test. Good design = performance, reliability, and maintainability. 🔹 Key Principles Scalability – Can the system handle 1 user… or 1 million? Fault Tolerance – If part of the system fails, does the rest keep running? Readability – Clean, modular code that others can understand. Extensibility – Easy to add new features later. 🔹 Example: Designing a Simple URL Shortener Imagine building a Java-based URL shortener (like Bitly). Requirement: Convert long URLs into short ones. Approach: Use Hashing or Base62 encoding for unique IDs. Store mapping in a database (MySQL/NoSQL). Implement caching (e.g., Redis) for faster reads. Java Code Snippet import java.util.HashMap; public class UrlShortener { http://short.ly/"; public String shorten(String longUrl) { String key = Integer.toHexString(longUrl.hashCode()); map.put(key, longUrl); return BASE + key; } public String expand(String shortUrl) { String key = shortUrl.replace(BASE, ""); return map.getOrDefault(key, "URL not found"); } } 🔹 Patterns to Know for Interviews Singleton → For global resources like DB connections. Factory → For object creation flexibility. Observer → For event-driven systems. Builder → For constructing complex objects step by step. 🔹 Full System Design Guide I’ve written a detailed breakdown of Java system design with examples and code snippets here 👉 🔹 Final Thoughts System design is where Java knowledge meets real-world application. ✍️ Originally published via AnalogyAndMe.com  ( 6 min )

Preparing for Java interviews can feel overwhelming. You study OOP, memory management, exceptions, multithreading… but when you sit in front of the interviewer, nerves kick in. The secret? 👉 Analogies. 🔹 OOP Concepts: The Restaurant Analogy Class → Think of it like a menu. It defines what’s available. Object → An actual dish you order from the menu. Inheritance → A specialty restaurant that takes a base menu and adds its own flavor. Polymorphism → The same “dish” name, but prepared differently (spicy, mild, vegan). 🔹 Garbage Collection: The Janitor Analogy Garbage Collection in Java is like a janitor in a library. Readers (your program) borrow books (objects). When no one needs a book anymore, the janitor quietly clears it away. You don’t control when it happens—but you trust it to keep the library clean. 🔹 Multithreading: The Airport Analogy Imagine an airport with multiple runways. Each plane is a thread. The air traffic controller (CPU scheduler) decides who takes off and when. More runways = more concurrency, but too many planes at once causes chaos. 🔹 Why Analogies Work in Interviews They show you truly understand the concept (not just memorized definitions). They make your answers stand out compared to robotic textbook replies. Interviewers love candidates who can explain complex topics simply. 🔹 Full List of Analogies I’ve compiled a detailed guide of Java interview questions explained with analogies here 👉 🔹 Final Thoughts Whether it’s OOP, threads, or garbage collection, analogies stick. ✍️ Originally published via AnalogyAndMe.com  ( 6 min )

When it comes to Java, few things spark more debate in developer interviews than “Which version do you prefer—Java 8 or Java 17?” Both are milestone releases, but their features, performance, and interview relevance differ in key ways. Let’s break it down. 🔹 Java 8 – The Old Reliable Released in 2014, Java 8 revolutionized coding style with: Lambdas & Streams → Functional programming in Java Optional Class → Handling nulls more gracefully Date & Time API (java.time) → Finally, a modern replacement for Date For many companies, Java 8 is still in production, so interviews often test candidates on these fundamentals. 🔹 Java 17 – The Modern Powerhouse Fast forward to 2021, and we get Java 17, a long-term support (LTS) release packed with improvements: Sealed Classes → Better inheritance control Pattern Matching → Cleaner and safer type checks Text Blocks → Simplified multi-line strings New Garbage Collectors → ZGC & G1 for performance boosts Security & Performance → Stronger out of the box 🔹 Which One Should You Learn? If you’re preparing for interviews → Master Java 8 + Java 17 differences. Interviewers love to test migration knowledge. If you’re working on modern projects → Go for Java 17. It’s faster, more secure, and future-proof. 🔹 Side-by-Side Quick View Feature Java 8 Java 17 Lambdas & Streams ✅ Introduced ✅ Still relevant 🔹 Read the Full Comparison I’ve written a detailed, interview-focused breakdown of Java 8 vs Java 17 here 👉 🔹 Final Thoughts Java 8 → Still important, especially in interviews. Java 17 → Future-ready, packed with features, and here to stay. If you’re serious about Java interviews or upgrading your skills, understanding both is non-negotiable. ✍️ Originally published via AnalogyAndMe.com  ( 6 min )

Initially I struggled to find the right approach to the problem. I used 3 pointers thought it would save the performance cases. But I was wrong there, this is a two pointer problem after sorting.

The Internet of Things (IoT) connects everyday devices such as sensors, smart appliances, wearables, and industrial machines to the internet, enabling seamless communication and automation. While this interconnectivity provides convenience, efficiency, and innovation, it also raises significant concerns about user data privacy. IoT devices constantly collect vast amounts of sensitive information, including health data, location details, personal habits, and even financial transactions. Unlike traditional systems, IoT devices often have limited computing power and security capabilities, making them more vulnerable to cyberattacks. Additionally, the fragmented ecosystem of IoT where multiple vendors and platforms operate creates interoperability issues that can expose data during transmission. In many cases, users are unaware of how much data is collected, how long it is stored, and who has access to it. Weak encryption, inadequate authentication, and insufficient regulations further amplify the risks. A single compromised IoT device can act as a gateway, exposing entire networks to malicious intrusions. Thus, ensuring user data privacy in IoT requires stronger encryption standards, transparent policies, and secure-by-design approaches. Anyone seeking deeper knowledge in this domain can benefit from structured learning, for example through an IoT certification course.  ( 5 min )

Claude knows about your Stripe webhooks, your database schema, that weird edge case with European VAT. Life is good. Then your PM pings you. Production bug. Critical. Drop everything. git stash git checkout main git checkout -b hotfix/critical-bug-fix You open Claude Code and... it's still talking about Stripe webhooks.

Gut feelings are good. But data makes them stronger. As Project Managers, we often rely on our intuition to make quick calls. That’s important — but without data, intuition can feel like guesswork. Every decision we make affects the budget, the timeline, and the team. That’s why I lean on data; whether it’s through simple dashboards, risk logs, or performance metrics. With data, we don’t just manage projects… ✅ We start to see the patterns. At the end of the day, data doesn’t replace leadership — it makes us better leaders. 💡 I’m curious, how do you use data to support your project decisions?

Decoding the Mystery: Bias-Variance Trade-off in Machine Learning Imagine you're trying to hit a bullseye with darts. Sometimes you miss wildly (high variance), other times you consistently hit the same spot, but far from the center (high bias). The perfect throw lands consistently close to the bullseye – a balance between bias and variance. This analogy perfectly captures the essence of the bias-variance trade-off in machine learning. It's a fundamental concept that dictates the accuracy and generalizability of our models, and understanding it is crucial for building effective and reliable machine learning systems. In machine learning, the goal is to build models that accurately predict unseen data. However, models are prone to two types of errors: Bias: This refers to the error introdu…  ( 9 min )

Introduction: Why Memory Allocation Matters in Go Hey Gophers! If you’re building high-performance apps in Go—think microservices, API gateways, or real-time data pipelines—memory allocation can make or break your system. Frequent allocations of small objects (like structs for JSON parsing) can hammer your garbage collector (GC), while large objects (like buffers for file uploads) can spike memory usage and crash your app with out-of-memory (OOM) errors. Sound familiar? Imagine your app as a busy warehouse: small objects are like tiny packages cluttering shelves, causing fragmentation, while large objects are bulky crates eating up space. Go’s memory allocator, inspired by tcmalloc, is built for speed and concurrency, but without the right strategies, you’re leaving performance on the ta…  ( 14 min )

I recently came across a LinkedIn post about a typo squatting attack which transcended the well-known IDN homograph attacks (e.g: Latin, Greek, Cyrillic). The malicious actor was using the Japanese character ん. Intrigued by the meaning of this, I made a research and discovered it translates into "yes" (that's why title "ん, and?", similar to Ariana Grande's viral song "Yes, And?"). The victims receives a phishing email which seems to originate from Booking. In fact, the adversaries masqueraded (T1036) the legitimate company. According to a data breach report issued by Verizon, phishing (T1566) is the 3rd technique to obtain initial access (TA0001), being involved in 17% of breaches. Analyzing the e-mail, one can observe elements such as: general greeting (Dear Partner) the same greeting…  ( 7 min )

Yeah, me too. That's exactly why I built PhotoPro. Here’s the thing: I’m not a professional photographer. And photo editing? Even worse. Because to “properly” edit photos you apparently need to know: What filters and sliders actually do When to use brightness vs. exposure vs. gamma (yes, that’s a thing) Color theory (whatever that is) Guess what?

After years of development hell, Bloodlines 2 finally delivers a slick mystery dripping with atmosphere, top-notch voice acting and fun parkour-style traversal through Seattle’s gothic streets.

In this blog post, we'll tackle some interesting coding questions related to Kotlin generics. But first, let's quickly recap the fundamentals. Generics in Kotlin allow us to write classes, interfaces, and functions with a placeholder for a type, so as to create reusable and type-safe code that can work with different types. Kotlin has declaration-site variance(with the generic class or interface's declaration) and use-site variance, aka type projections(in function signature). out - keyword used to mention the type is a producer(can return values of type T). in - used to mention the type is a consumer(can accept values of type T). where - used to indicate that the type has more than one constraint. reified - to preserve the type information at runtime, facilitates safe type-check with 'is'…  ( 8 min )

In 2025, the demand for fast, SEO-friendly, and dynamic web experiences is stronger than ever. While client-side rendering still powers many web apps, server-side rendering (SSR) has reemerged as a key architectural choice — thanks to modern tooling, improved performance, and better developer ergonomics. Two of the most prominent SSR frameworks today are Nuxt.js, built on Vue, and Next.js, built on React. Both have matured significantly over the past few years, offering hybrid rendering capabilities, powerful module systems, and support for modern edge infrastructures. But which one should you choose for your next project in 2025? In this article, we’ll explore the state of SSR today, evaluate the strengths and trade-offs of Nuxt and Next, and help you decide based on your project’s needs.…  ( 8 min )

BootstrapVue was once the go-to choice for combining Bootstrap with Vue. But times changed: Vue 3 became the standard, Bootstrap 5 took over, and BootstrapVue itself stopped evolving. So what now? Enter BootstrapVue Next – a community-driven project that tries to fill the gap. But the real question is: is it mature enough to replace the original? Supports Vue 2 only – incompatible with modern Vue 3 projects. No Bootstrap 5 support – stuck with Bootstrap 4. Development has stalled – no bugfixes, no new features for years. Increasing security & compatibility risks. And yet… BootstrapVue still shows ~176,000 weekly downloads on npm. Why? Many legacy projects are still running on Vue 2 and won’t migrate anytime soon. Some companies prefer the stability of “old but proven” libr…  ( 6 min )

It's everywhere, it's eating up every other dev topic debate: learn to dev with AI or you'll be replaced. As a dev, I can't help but feel threatened by these claims. Way more than I should.

I felt so clever when I automated ticket creation with Jira MCP with full codebase and commit history knowledge. I felt not so clever when my "instant" refactoring took me a full day to review and rewrite to fix "just that little bug". I love automating my work as much as the next dev, but I also love to measure the results of automation.

You Don’t Wait for Ideas. You Engineer Them. "You can generate ideas at will." Ideas don't just fall from the sky. They emerge from systems you weren't tracking. You might call an idea "random" because: Your awareness was offline, or Your model of cognition is too shallow. But just because you didn't witness the mechanism doesn't mean there wasn't one. Your mind is a computational pattern-detector. Every idea ever formed requires three things: Inputs: Data, memory, tension, contradiction, observation Processing: Association, compression, contrast, iteration Output: A coherent novelty This is the fundamental frame: Input → Throughput → Output Even when unconscious, your mind still runs this pipeline.

If you are new to cybersecurity or penetration testing, one term you will encounter frequently is wordlist. Understanding what it is and how to use it effectively is important before diving into tools like Crunch. A wordlist is simply a collection of words or phrases, usually stored in a text file. In cybersecurity, wordlists are most commonly used for password cracking. Tools like John the Ripper or Hashcat use wordlists to try different passwords against a target system. Think of a wordlist as a giant set of possible keys you can try to unlock a door. The more relevant and targeted the words, the higher your chances of success. There are prebuilt wordlists available online, like the famous rockyou.txt, but sometimes you need something custom. That is where Crunch comes in. Passwords ofte…  ( 7 min )

I’ve been working in software testing for over 10 years — from manual QA to automation and now leading QA teams. Over this time, I’ve seen how fast the industry evolves. But nothing has accelerated change in testing as much as AI 🤖. As a QA Lead & Manager, I use AI every day to speed up testing, reduce repetitive tasks, and make smarter decisions for my team. Here are my top 5 ways AI is transforming QA leadership: 1️⃣ Smarter Test Prioritization AI helps leaders focus on what matters most by predicting which test cases are critical based on risk and past failures. No more guessing — data-driven decisions win. 2️⃣ Accelerated Test Automation Instead of spending hours writing boilerplate scripts, AI-assisted tools generate tests automatically. This frees my team to focus on strategy and innovation ✨. 3️⃣ Enhanced Defect Prediction By analyzing historical bug data, AI can predict where defects are most likely to appear. This means we can allocate resources better and improve release confidence. 4️⃣ Intelligent Test Maintenance One of the biggest pains in QA is flaky or outdated tests. AI-driven tools can self-heal scripts, reducing maintenance time and frustration for the team. 5️⃣ Data-Driven Leadership For me as a QA Lead, AI provides dashboards and insights that help in reporting, team planning, and decision-making. It’s not just about testing faster, but leading smarter 💡. 🌍 The Future of QA Leadership AI isn’t replacing testers — it’s empowering us to focus on higher-value work: critical thinking, quality strategy, and leadership.

"How hard could it be to detect when someone presses Ctrl+C?" Famous last words before a 3-day deep dive into VS Code's internals. Sometimes the simplest requirements lead to the most fascinating technical challenges. This is the story of how I learned to intercept VS Code commands without breaking everything. Detecting keybindings in VS Code requires intercepting commands, parsing keybinding configurations, and handling edge cases. Here's how I built a robust system that monitors 70+ commands without affecting performance or user experience. The requirement seemed straightforward: "When a user presses Ctrl+C, show a notification." My initial naive approach: Listen for keyboard events ⌨️ Detect Ctrl+C combination 🔍 Show notification 📱 Profit! 💰 Spoiler alert: This approach lasted exac…  ( 12 min )

Statistics in Tableau Data in the right hands can be extremely powerful and can be a key element in decision making. American statistician, W. Edwards Deming quoted that, “In God we trust. Everyone else, bring data”. We can employ statistical measures to analyze data and make informed decisions. Tableau enables us to calculate multiple types of statistical measures like residuals, correlation, regression, covariance, trend lines and many more. Today let’s discuss how people misunderstand causation and correlation using Tableau. Correlation is a statistical measure that describes the magnitude and direction of a relationship between two or more variables. Causation shows that one event is a result of the occurrence of another event, which demonstrates a causalrelationship between the two …  ( 8 min )

Why Zig Could Be the Future of Systems Programming in 2025 When people talk about systems programming, C and Rust often dominate the conversation. But there’s another contender silently gaining attention: Zig. While still under the radar for many developers, Zig is quickly proving to be a language that could change how we think about building fast, reliable, and low-level software. Zig is designed with simplicity, predictability, and control in mind. Unlike Rust, which focuses heavily on ownership and borrowing, Zig takes a different route: Manual memory management (without being painful) No hidden control flow Cross-compilation built into the language Readable error handling with try instead of exceptions It’s not about reinventing the wheel — Zig is about giving develope…  ( 6 min )

Intro – APIs + automation use cases APIs make it easy for software to talk to software. With a few HTTP calls, you can move data between tools, trigger workflows, and generate reports without manual steps. Common automation use cases: Lead capture → CRM: Send a form submission into HubSpot or Salesforce. E‑commerce → accounting: Post new orders to your bookkeeping system. App events → Slack/Email: Notify teams instantly when important events occur. User actions → spreadsheets: Log signups or errors into Google Sheets for quick analytics. You’ll build a small, practical pipeline: when a new user signs up, a Python script sends their data to Google Sheets via a webhook URL. Then you’ll optionally enrich those users with a second API and handle authentication securely. Goal: Every time a ne…  ( 9 min )

Intro – webhook vs API polling APIs let you fetch data on demand; polling is when your system repeatedly asks, “Anything new yet?” at a schedule. Polling is simple but inefficient: you waste requests when there’s nothing to fetch, and you discover changes only after your next poll. Webhooks invert the flow. Instead of you polling, external systems call your endpoint immediately when something happens e.g., Stripe charges succeeded, GitHub push events, or a CRM contact update. The result is: Faster reactions (near real-time). Lower infrastructure and API costs (no wasteful polling). More scalable automation (events drive workflows). A good webhook receiver must be reliable, secure, and fast: accept the request, verify authenticity, enqueue work, and return 2xx quickly. Think of a five-ste…  ( 9 min )

Why automated tests matter Automated end-to-end (E2E) tests give you confidence that core user flows like login, signup, checkout, and profile updates work every time. They: Catch regressions early: Breakages are detected before production. Speed up releases: CI runs tests on every pull request. Document expected behavior: Tests double as living documentation. Reduce manual QA: Engineers focus on higher-value work. Cypress is a developer-friendly E2E framework that runs in the browser, offers great debuggability, and has first-class tooling for network control, retries, and time-travel debugging. Below, you’ll find a full login test you can drop into a project, plus a parallel Playwright example for comparison. npm install --save-dev cypress Optional but recommended scripts in package.j…  ( 10 min )

The Hidden Dangers of AI-Driven Automation: What We’re Overlooking Artificial Intelligence (AI) and automation are reshaping industries at lightning speed. From automated customer support to AI-generated code and self-learning supply chains, the push for efficiency is stronger than ever. But amid the excitement, there’s a darker, less-discussed reality: the unintended consequences that could leave lasting scars on our workforce, privacy, and even human creativity. When machines begin performing tasks humans once mastered, we risk losing essential skills. Think about pilots who now rely heavily on autopilot or developers leaning entirely on AI coding assistants. Over time, these abilities atrophy, leaving professionals less prepared when automation fails. Most discussions about AI and…  ( 6 min )

If you’ve ever worked with scroll events, search boxes, or API calls in JavaScript, you’ve likely faced the issue of functions running too often and slowing down your app. That’s where Throttle and Debounce come to the rescue! In this blog, I’ll explain the difference between throttle and debounce with real-world examples, code snippets, and when to use each one. 🔹 What is Debounce in JavaScript? Debounce makes sure a function runs only after a certain time has passed since the last call. 👉 Think of typing in a search box. You don’t want to call the API for every single keystroke. Instead, you want to wait until the user stops typing. ✅ Example: function debounce(func, delay) { let timeout; return function (...args) { clearTimeout(timeout); timeout = setTimeout(() => func.app…  ( 6 min )

Everyone's building AI agents these days, and everyone's teaching you how to do it in Python or JavaScript. Nothing wrong with Python. It's fast to prototype with and has a mature ecosystem.

Introduction Over the past couple of years, I've been observing a trending phenomenon on X (Twitter): "build in public." Developers building products share screenshots, code snippets, and progress updates from their projects, posting them with the hashtag #buildinpublic.

I believe that #buildinpublic should be truly public, with projects being open sourced from day one. That's why I'm excited to announce my new open source project flow-run, which I'll build completely in public and document every step of the journey. The source code will be available on GitHub from the very first day of development. The idea for this project was inspired by my previous product ai-svc, developed for…  ( 9 min )

Running a limited company in the UK brings many advantages, such as limited liability, greater credibility, and potential tax efficiency. However, it also comes with important tax responsibilities that directors must manage carefully to remain compliant with HMRC and Companies House. Every limited company must pay Corporation Tax on its taxable profits. This includes profits from trading, investments, and chargeable gains. Unlike sole traders, companies do not get a personal allowance; Corporation Tax is charged on the full amount of profits. Registration: A company must register with HMRC for Corporation Tax within three months of starting business activity. Payment Deadline: Corporation Tax must usually be paid within 9 months and 1 day after the end of the accounting period. Filing: The…  ( 6 min )

Introduction In today's blog we conclude on the Understanding Java Data Type series. We will be covering char and boolean types in java. So without further delay let's get into it. In Java, it is useful to think of a char as a small box that can hold one number between 0x0000 and' 0xFFFF` (these numbers are written in hexadecimal). Technically speaking, a Java char is a single 16-bit code unit from UTF-16. surrogate pair). That’s why a char is not always “one visual character.” Think of it this way, certain symbols are too large to fit into char's single box hence they bring a second box to help accommodate them. (Hence, they become surrogate pairs). Once they become surrogate pairs they are now strings but not char. Useful Tip: When you need to handle characters (as people think of t…  ( 7 min )

Decorators: when used well, they make code cleaner. But to the uninitiated, they can turn the mysterious into the totally inscrutable. A decorator is essentially a function that can alter the behavior of another function or class, without altering its code. You can add functionality like timing a function or logging its output, or completely change what the function does. The @dataclass decorator, added before a class meant to hold data, automatically adds common methods for dealing with that data: an __init__() constructor that accepts parameters to create a class instance a __repr__() method that outputs a string representation of the instance __eq__() for testing equality of two class instances __hash__ allows the data in your class to serve as dictionary keys--assuming the data is hashable and frozen=True if you set order=True, you can use comparison methods such as __lt__ (less than), __le__ (less than or equal to), __gt__ (greater than), __ge__ (greater than or equal to) First you from dataclasses import dataclass in your code, then you add @dataclass right before your class definition: @dataclass class Article: title: str author: str description: str url: str source: str published_at: datetime.now.strftime("%Y-%m-%d %H:%M:%S") Your class now comes with all of the above methods, saving you the headache of writing them all out.  ( 5 min )

Minimum Monthly Average Balance (MAB) It is the amount a bank account holder must maintain in their savings or current account during a calendar month. If the balance falls below this requirement, the bank imposes a penalty charge. An annual fee is charged for holding a debit card, usually between ₹100 and ₹500 depending on the card type. These renewal charges apply once the card reaches its expiry date. If a debit card is lost or damaged, banks charge ₹100 to ₹250 for issuing a replacement card. Cash transaction limits, including both deposits and withdrawals (by self or third party), are typically capped at 3 to 5 free transactions per month. Beyond this, banks may charge ₹100 per transaction. For cash transactions exceeding ₹2,00,000 in value in a month (including both deposit and wi…  ( 6 min )

"Why build yet another workflow app? And why on earth in a TUI?" That’s the question I asked myself when I started this project. Over the years, I’ve tried countless tools – task trackers, kanban boards, Notion setups – but most of them felt heavy, clicky, or distracting. I wanted something much simpler: a workflow manager that lives entirely in the terminal, fully keyboard-driven, fast, and with zero context switching. At first, I hacked together a prototype using plain curses. It worked… kind of. But as the project grew, I realized I needed something more structured and maintainable. That’s when I discovered Textual, and decided to port everything over. So far, Glyph.Flow can: define hierarchical workflows (Project → Phase → Task → Subtask), save/load the entire structure as JSON, render trees, tables, and ASCII views, and handle commands like create, edit, delete, search, toggle. The latest milestone (v0.1.0a4) brought two major improvements: a layered logging system with INFO/WARNING/ERROR/SUCCESS/HELP levels a command history module, so you can navigate previous inputs with the arrow keys. Why might this be interesting? Terminal-native. It feels more like working with your projects than managing them through a UI. 👨🏻‍💻 Personal journey. For me, this is not just a tool – it’s a playground to learn Textual, experiment with structured logging, and design clean extensible systems. Next steps: Command registry (auto-help, cleaner dispatch) Undo system (basic memento stack) Better error handling Export/import & statistics And eventually… a polished Textual TUI dashboard This is still very alpha – but it’s already fun to use, and I’m excited to share the journey here. 👉 You can check out the repo here: GitHub These changes laid the foundation for the next big step: the command registry, which will finally eliminate the infamous elif chain and make adding new commands a one-file operation.  ( 6 min )

There’s a new breed of “developer” loose in the wild. They don’t know what a POST request is, but they’ll ship an AI-generated SaaS app by the weekend. They can’t explain how routing works, but they’ve got a Vercel link with a slick dark mode and a gradient button. They’re not engineers. They’re vibecoders. These people aren’t using AI to assist their workflow. They’re outsourcing their thinking entirely — letting Cursor write full apps while they blindly accept suggestions like it’s Clippy from hell. They don’t debug. They just paste harder. When something breaks, they don’t ask why. They ask AI to fix what AI broke — and then paste that too. They can’t solve FizzBuzz, but they’ll happily yeet users’ data straight into the nearest black hole — or worse, leave it sitting wide open in a p…  ( 7 min )

As AI continues to advance, integrating Large Language Models (LLMs) with physical devices interpreting data, acting on environmental input, and responding contextually, has become increasingly feasible. Yet, LLMs often remain detached from the real world, limited by the absence of live sensory input or direct device control. The Model Context Protocol (MCP), launched by Anthropic in November 2024, addresses this gap by offering a standardized, secure way for AI systems to interface with external tools, data systems, and IoT devices. Think of MCP as a "USB‑C port for AI" a universal connector that simplifies integration across diverse contexts 123.

For decades, economic forecasts leaned on what was easy to measure: sales, jobs, inflation, inventories. Useful, yes—but often late. By the time those indicators arrive, the mood that drives consumer behavior has already shifted. In my GDP-forecasting work, I’ve seen a simple truth play out again and again: people’s expectations move before the numbers do. Today, with modern NLP and a flood of real-time text data, we can finally quantify that mood—and fold it into forecasts that react in weeks, not quarters. Sentiment is signal—if you treat it like a dataset, not a vibe “Sentiment” isn’t about gut feel; it’s a structured signal hiding in language.

Here's how a little laziness cost me $78. While working on a personal project recently, I wanted Cline to process about a hundred files that were each in subdirectories of a project. I fired up Cline and picked Gemini 2.5 Pro (context window FTW) and asked it to recurse through the subdirectories, process the files, and put the results in a new file. Cline got to work… slowly. I watched as the "API Request…" spinner appeared for each file read and each time it saved the results. About twenty minutes and $26 later, it finished. Okay, I thought, that's not great, but not untenable. The cost of convenience, right? I opened up the results file to take a look and.. sigh. Not great work. It was obvious that some files had been skipped despite my very careful instructions to process each and ever…  ( 8 min )

El método hashCode, es heredado de Object, normalmente de forma indirecta, y su utilidad principal es devolver un entero que representa al objeto.

This project demonstrates how to create an Azure Resource Group using Terraform modules. By using modules, we can organize our code better, promote reusability, and simplify management of infrastructure. parent_module/ main.tf (in parent_module directory) This is the root configuration file where we call our module. module "rg_create" { source = "../modules/resource_group" rg_name = "mademi-rg1" rg_location = "centralus" } module "rg_create" → Declares a module block named rg_create. source = "../modules/resource_group" → Points to the directory where our module is located. rg_name → Resource Group name passed to the module (mademi-rg1). rg_location → Azure region where the Resource Group will be created (centralus). This file defines the actual resource that Terraform w…  ( 6 min )

import pandas as pd We start with two data frames like those: df1 = pd.DataFrame( { "id_left": [1, 2, 3], "first_name": ["Alice", "Bob", "Charlie"], "last_name": ["Smith", "Jones", "Brown"], } ) df2 = pd.DataFrame( { "id_right": [1, 2, 3], "last_name": ["SmithX", "JonesX", "BrownX"], "age": [25, 30, 35], } ) Specifically: df1 id_left first_name last_name 0 1 Alice Smith 1 2 Bob Jones 2 3 Charlie Brown And, df2 id_right last_name age 0 1 SmithX 25 1 2 JonesX 30 2 3 BrownX 35 Next, we want to merge these two data frames. But, note that the column last_name appears in both AND they contain different values. This can happen when the left table is obtained using one processing flow and the right table using another flow. This way or the other, the described situation leads to an ambiguity which in turn leads to a challenge. For example, in Spark you will need to be very careful when working with the resulting data frame. Let's merge: df1.merge(df2, left_on="id_left", right_on="id_right", how="left") id_left first_name last_name_x id_right last_name_y age 0 1 Alice Smith 1 SmithX 25 1 2 Bob Jones 2 JonesX 30 2 3 Charlie Brown 3 BrownX 35 Nice! The columns with the identical names were suffixed with _x and _y respectively. This is thanks to the default values of the parameter suffixes. You can find it in the documentation. Personally, I find it rather smart solution that adheres to the Python principal of "explicit is better than implicit". What do you think?  ( 6 min )

Hi everyone! It's Creator X here. I wanted to share my experience transitioning my cyberpunk RPG Black Market Protocol from Ink.js to Phaser.js, and the technical challenges I faced along the way. When I started Black Market Protocol, Ink.js seemed perfect for a text-based narrative game. But as the game grew more complex, I hit some major limitations: The Function Integration Problem: Every game mechanic required: An Ink function in the story file A JavaScript bridge function Manual state synchronization between both This worked fine for simple story choices, but became a nightmare when trying to implement complex systems like dynamic combat, inventory management, and realistic hacking mechanics. As the story progressed deeper, managing these connections became exponentially harder. Here…  ( 8 min )

Real-time multiplayer card games are deceptively complex. On the surface, they look like simple turn-based systems with shuffled decks and straightforward rules.

🧠 The Hidden Power of AI Agents in Web Apps: Build a Truly Smart App in Less than 100 Lines of Code Imagine your web app actually thinks. Not just a chatbot. Not just GPT copy-paste. A decision-making, task-managing, user-adapting digital assistant. Welcome to the world of AI agents inside web apps — and yes, we’re doing it in under 100 lines of code. Unlike a simple chatbot or LLM wrapper (like GPT in a textarea), an AI Agent has: Goals – It wants something. Memory – It remembers what it did or said. Tool use – It can use APIs and resources. Decision-making – It can plan and change direction. Think of ChatGPT on steroids — mixed with Jarvis from Iron Man. If your app depends on communicating with users, managing tasks, or transforming data — you can basically automate it with an agent…  ( 7 min )

When a Book Feels Like a Hug Some books don’t just sit on your shelf—they sit with you when your mind feels heavy. I remember picking up It’s Okay To Not Be Okay on one of those restless nights. At first, I thought, “It’s just another self-help book.” But page by page, it felt like the author was holding my hand, telling me the things I had forgotten to tell myself: you’re not alone, your feelings are valid, you’re allowed to rest. That’s the power of mental health books. They don’t shout solutions at you. They whisper reminders you secretly needed: breathe, slow down, forgive yourself. Sometimes, it isn’t about finishing the whole book. Even one paragraph, read at the right time, can feel like sunlight breaking through a cloudy sky. Maybe that’s why I keep these books close. Not as answers, but as gentle companions for the journey within.  ( 5 min )

🔥 From Arduino to Mars: Why You Should Be Using TinyGo for Embedded Web Development If you’ve ever attempted to build something that lives at the intersection of embedded systems and the modern web — say, a microcontroller that serves a WASM-powered control dashboard over HTTP — you’ve probably run into some harsh realities: C is painful. Rust is powerful, but finding embedded libraries that just work is a chore. JavaScript, while king of the browser, isn’t welcome on your $2 MCU. Is there a better way? What if you could use Go, a modern compiled systems language with safe memory handling and a thriving toolset, to build for microcontrollers AND compile to WebAssembly (WASM)? Let me introduce you to TinyGo — the smallest, fiercest, and most fun way to build projects that live somewhere …  ( 8 min )

If you understand how languages and compilers actually work, you’ll write better code and learn new languages more easily. There are 2 types of software engineer: those who understand computer science well enough to do challenging, innovative work, and those who just get by because they’re familiar with a few high level tools. Both call themselves software engineers, and both tend to earn similar salaries in their early careers. But Type 1 engineers progress toward more fulfilling and well-remunerated work over time, whether that’s valuable commercial work or breakthrough open-source projects, technical leadership or high-quality individual contributions. Type 1 engineers find ways to learn computer science in depth, whether through conventional means or by relentlessly learning throughout their careers. Type 2 engineers typically stay at the surface, learning specific tools and technologies rather than their underlying foundations, only picking up new skills when the winds of technical fashion change. Currently, the number of people entering the industry is rapidly increasing, while the number of CS grads is relatively static. This oversupply of Type 2 engineers is starting to reduce their employment opportunities and keep them out of the industry’s more fulfilling work.

If you blinked last weekend, you missed the most explosive 48 hours in tech this decade. While most of us were enjoying our weekend, the AI world was busy completely losing its mind. Friday afternoon, OpenAI just... dropped GPT-5. No grand announcement. No weeks of hype. Just "hey, here's the future." Early testers are calling it a quantum leap beyond GPT-4. We're talking about an AI that can handle complex mathematical reasoning, advanced scientific concepts, and problem-solving that actually makes sense. Sam Altman's quote says it all: using GPT-4 now feels "miserable" by comparison. But here's the reality check: it still can't learn on its own. We're closer to AGI, but we're not there yet. Remember when everyone said China was "years behind" in AI? Plot twist: They're not anymore. The…  ( 7 min )

I would never recommend going straight into freelancing. Get a job instead. Freelancing is significantly harder than most people would have you believe. As a freelancer, you’re responsible for everything. This includes running a business, protecting yourself (legally), sales, marketing, and much more. Selling services is an art in and of itself. Most sales come from having a strong network of people who would hire you. The reality is if you’re asking this question, you probably don’t have a large enough network to make a living. More importantly, most clients who seek freelancers are looking for people who can step in and get the job done quickly. They’re seeking experienced developers. Many developers come out of school or a bootcamp thinking they can make a ton of money in development. They’ve heard demand is high for software developers. Demand is only high for some kinds of developers. If you want to earn a solid wage, take a job. You’ll learn a lot while working for a company. You’ll have a steady paycheck. You’ll establish a network amongst your coworkers. Your company may even provide additional training or send you to conferences. You won’t have to find your own clients or deal with legal papers. You’ll probably even get health insurance! The best part is you’ll gain experience. If you decided to freelance in the future, you’ll be prepared. There is a stigma around freelancing that: 😏you can make more it’s total crap, especially when you’re starting out. It’s a struggle to get your first clients. Most people take whatever work they can get in the beginning. Clients are demanding, and they won’t treat you as well as an employee. Want to work with the latest tech?

Fintech apps can experience transaction spikes up to 10 times their normal volume during periods of rapid growth (Deloitte). For a payments or trading platform, that pressure can quickly expose the cracks in a poorly chosen tech stack. If the architecture isn’t built to scale, performance lags, outages, and even security vulnerabilities can follow, and in finance, losing reliability means losing trust. That’s why the decision about which tech stack to build on isn’t just technical. It shapes how well an app can handle compliance requirements, how quickly it can integrate with banking APIs, and how securely it processes sensitive financial data. The right choice makes scaling smoother and safer, while the wrong one can lead to costly rebuilds at the very stage when a startup should be growi…  ( 8 min )

Introduction: When we design applications in the cloud, it’s not just about running code. It’s about organizing layers, controlling access, and making sure everything scales smoothly. One of the best ways to do this is through a three-tier architecture. In this blog, I’ll walk you through how RDS fits into a three-tier app on AWS, and we’ll take a real-world Data Entry Portal as our example. A three-tier app is like a relay race. Each tier does its job, then hands over to the next: Web Tier – The entry point. This is where users connect through a browser. App Tier – The logic hub. It processes requests and applies business rules. Database Tier – The memory. It stores and retrieves data whenever the app needs it. On AWS, these tiers are usually split like this: Web Tier: EC2 instances beh…  ( 6 min )

Installing and Configuring Nginx as a Load Balancer Deploying a web application on a high-availability stack requires careful configuration to ensure seamless performance and scalability. This case study details the process of installing and configuring Nginx as a Load Balancer (LBR) to address performance degradation on a website due to increasing traffic. By following a structured approach, we successfully migrated the application and resolved critical configuration errors. The first step was to install Nginx on the designated Load Balancer (LBR) server. Nginx is a powerful open-source web server often used as a reverse proxy, HTTP cache, and load balancer due to its high performance and low resource usage. The installation process was straightforward using the server's package manager…  ( 7 min )

Goal Don’t aim to be the next “big thing”. Just aim to solve a problem that can help others. Helping others is the real reward, money typically follows. Help - Find a lawyer or if your neighbor is, talk with them to learn about any legal items you need to consider or consult an online forum. You most likely won’t need to pay a lawyer. Brand - Develop your brand. Buy a domain using the name of your brand and use a simple service like 99 designs to develop your logo and wix to build your site. If you want you can design your own logo, don’t spend more than $50. You don’t need to. Have a friend help you if designing is not your thing. Marketing - Focus on your customer. Learn all about them: their needs, their likes, dislikes, how your service can help them, what they need from you etc. Execution - Then deliver. Make it happen, enjoy the process and learn. Besides the reward of helping others which will help you feel good about yourself, the skills and things you learn along the way will be priceless. I’ve started a few companies and helped some along the way, and it’s a wonderful process. The more you do it, the better at it you get.

In Bash scripting, the wait command is commonly used when running commands in the background using the & symbol, allowing multiple tasks to execute concurrently. However, when the completion of one or more of those tasks is crucial for the next steps, the script must pause and wait. This is where the ‘wait’ command comes in. It halts the script’s execution until a specific background process, or all background processes, have completed. This ensures smooth automation by preventing race conditions and execution conflicts. Whether you’re downloading files, starting services, or managing timed operations, the ‘wait’ command helps keep reliable control over the flow of your script. Prerequisites A Linux environment or terminal with Bash installed Basic knowledge of shell scripting Access to create and execute ‘.sh‘ script files Bash ‘wait’ Command Syntax and Common Options You can use the ‘wait’ command in Bash with this basic syntax: wait [pid ...] Note: If no PID or job ID is specified, ‘wait’ pauses until all background processes are finished. Description When you use ‘&’, a command runs in the background. By default, the script continues executing. To pause the script until that background task finishes, use ‘wait’. Steps to Execute Create a script file: nano wait-single.sh Add the following code: #!/bin/bash Save and exit (Press ‘Ctrl + O’ (then press ‘Enter’ to confirm the filename), then press ‘Ctrl + X’ to exit). Make the script executable: chmod +x wait-single.sh Run the script: ./wait-single.sh Read full article: https://link.srvr.so/soarzcuc  ( 6 min )

While the tech world focuses on the impressive capabilities of cloud-based AI agents like ChatGPT and Claude, we're exploring a different question: Can we build truly intelligent AI agents that run entirely on users' local devices? The appeal is obvious: complete data privacy, zero network latency, freedom from service limitations, and genuinely personalized experiences. But the technical challenges are equally significant: limited local model capabilities, complex tool calling mechanisms, and ensuring consistent user experience. After extensive exploration, we've completed a major upgrade to NativeMind conversational architecture, taking our first significant step toward local AI agents.

This tutorial shows how to build a small, browser-based monitor that reads only the advertised noise level from a nearby HibouAir sensor using a BleuIO USB BLE dongle. There is no pairing, no audio recording, and no microphone access. The page simply listens for Bluetooth Low Energy (BLE) advertisements, decodes a numeric noise value emitted by the sensor, and renders it as a color bar between 40–80 dBSPL. When the value exceeds a threshold you choose, a plain “shhhh” banner appears as a gentle cue to keep things quiet. The goal is awareness, not surveillance. Many environments benefit from real-time feedback about loudness—libraries, classrooms, shared offices, and homes—yet microphones introduce privacy concerns and data-handling obligations.

Most developers start projects by creating their first file: main.py, index.html, or app.js. I start with README.md. This isn't about documentation best practices or making my repositories look professional. It's about forcing myself to think clearly before I write code that thinks for me. The README-first approach has saved me from countless architectural mistakes, scope creep disasters, and that special kind of technical debt that happens when you're not sure what problem you're actually solving. Here's what happens when you jump straight into implementation: you start solving for the solution instead of the problem.

Introduction “Do one thing well.” That’s the entire idea behind Pomora. It’s a simple Pomodoro timer with a clean UI, dark mode, and zero fluff—built with Next.js (App Router), TypeScript, Tailwind CSS, and shadcn/ui. Live demo: https://pomora.vercel.app/ https://github.com/shravzzv/pomora Two reasons: Build-every-week habit: I wanted a small but polished app to sharpen my Next.js + UI chops. Minimalism: Most timers do too much. I wanted a calm, unobtrusive tool I actually enjoy keeping open. No accounts. No dashboards. No backend. Just a good timer. Three modes: Pomodoro (25m), Short Break (5m), Long Break (20m) Controls: Start / Pause / Resume / Restart + Reset Smart time display: hh:mm:ss only when hours are needed Dark/Light themes with a settings dialog Responsive and accessible UI (buttons, focus, contrast) Privacy friendly: no backend; optional Vercel Analytics if you want it Next.js (App Router) + TypeScript Tailwind CSS for utility-first styling shadcn/ui for accessible primitives (Tabs, Dialog, Button, Switch) lucide-react for crisp icons Vercel Analytics Pomora is intentionally small. If you’ve been meaning to ship something, I highly recommend a scoped, well-designed utility like this. You’ll finish faster and learn a lot on polish. If you try it, I’d love feedback.  ( 6 min )

New frameworks, APIs, and cloud platforms are popping up every month, and it’s easy to feel like you’re always playing catch-up. But here…  ( 8 min )

TL;DR Drunk Transformer (DT) simulates a transformer that sometimes behaves “drunk” — hallucinating, drifting, or jumping logic — and then regulates it back on track using five lightweight checks you can run as prompt rules, decoding hooks, or training regularizers. In WFGY 2.0, DT is one of the core reasons our text-to-image steps stay on-topic, stable, and geometrically precise rather than spiraling into semantic chaos. Modern LLM/T2I stacks are powerful but fragile. A small nudge can push them off-topic, over-confident, or into branch jumps that the user never asked for. DT treats this as a control problem: let the model roam, but continuously measure where it is and nudge it back with principled signals. We measure semantic distance between intent and guess (δₛ). We watch anchor retent…  ( 9 min )

👨💻 My Daily Tech Stack as a Frontend Engineer Every day when I sit down to code, I love having a toolkit that feels reliable, efficient, and flexible. Over time, I’ve curated a stack that helps me build everything from small utilities to full-scale applications.

There are two constants in software development: Deadlines that make no sense The phrase “works on my machine” If you’ve been in the trenches long enough, you’ve heard it. Maybe you’ve even said it (shame on you). It’s the universal excuse, the verbal shrug that says “I washed my hands of this problem. May the production gods be with you.” It’s the tech equivalent of this AAA story I once heard: And yet, “works on my machine” keeps haunting us. Why should we keep pretending? Let’s make it official: a Jira status. Imagine the workflow: To Do In Progress In Review Works on My Machine Blocked Done Because honestly, half of the time, that’s where tickets live anyway. Here’s what “Works on My Machine” really means: Dev Environments Are Snowflakes Everyone’s running a slightly different version of Node, Java, Docker, or whatever fresh hell your stack requires. Your laptop is not production—it’s a theme park simulation of production, with fewer rides and more exceptions. We Treat CI/CD as a Suggestion If every commit doesn’t go through the same build and deploy pipeline, congrats—you’re running a volunteer fire department for bugs. No One Owns Infrastructure Developers blame Ops. Ops blames developers. QA just cries quietly in the corner. Meanwhile, the business wonders why the “simple fix” took three days and a therapy session. But here’s the kicker: the business doesn’t care if it works on your machine. They care if it works in production, for actual paying users, without setting fire to servers like it’s Guy Fawkes Night. So yes, let’s add “Works on My Machine” as a Jira status. At least then, we’d have an honest reflection of the mess. Transparency is the first step toward fixing it. Or—and here’s a crazy thought—we could stop treating DevOps as a luxury. Until then, I’ll keep clicking refresh on Jira tickets stuck in limbo, whispering: “Fly free, little bug. May you one day work somewhere else.”  ( 6 min )

A few years ago, I launched my first web app. The design was slick, features worked well, and users were signing up fast. 🚀 But then one day, I woke up to an email: “Your app has been compromised. User data has been leaked.” My heart sank. 💔 I didn’t use proper hashing for passwords. I didn’t add two-factor authentication. Worst of all, I thought “a simple login form” was enough. That mistake nearly destroyed my project—and my reputation. That experience taught me one unforgettable lesson: In this post, I’ll break down authentication and authorization in simple terms, share actionable tips you can implement today, and show you how to secure your system like a pro.

Sunflowers on a mission: better English in linear time? Hi! I'm Asparagos — an asparagus who codes in Go. Here you’ll find everyday problems that a typical veggie might struggle with — and my Go solutions to them. Today we are solving the problem of Sunflower Speaking Club 🌻. Sunflowers are planning to expand their influence across the world. Olives are gaining popularity, they can’t fall behind. To achieve this, they need to learn English. Each sunflower already speaks it to some extent, but wants to find a partner to practice with. The sunflowers are planted in a row. Each has their own level of English and wants to find the nearest sunflower to the right who speaks better than they do. Why to the right? The sun is rising in the east, so it’s the perfect moment to combine business with …  ( 7 min )

Curious about how I ended up with an invoice nearing $100 for conducting over 20 million Class A operations on Cloudflare R2? I initiated several Litestream processes across a variety of side projects and forgot to set the sync interval! :) It defaults to 1s The backup I was handling was more complex than the main production database. It included slight variations in the SQLite file because it automatically queried various external services to check the status of different entities. Just add: sync-interval: 4h to the replica section. Here is a full example: dbs: - path: /mnt/goodenoughtesting/current/storage/production.sqlite3 replicas: - type: s3 bucket: $GOOD_ENOUGH_TESTING_BACKUP path: production access-key-id: $LITESTREAM_ACCESS_KEY_ID secret-access-key: $LITESTREAM_SECRET_ACCESS_KEY endpoint: $LITESTREAM_REPLICA_ENDPOINT region: auto sync-interval: 4h  ( 5 min )

Wired internet on a game console feels boring until you actually use it. Stable lobbies, cleaner voice chat, faster downloads, fewer disconnects during ranked play. If you switch between handheld and TV mode a lot, you already know how Wi‑Fi can wobble the moment someone streams a 4K movie in the next room. A simple cable can level that out. We’ll walk through what works on the original model, the OLED refresh, and the newer Switch 2, plus the exact setup steps and a checklist for buying the right gear. No brand chasing, just practical specs and settings that keep your connection solid so you can focus on playing, not troubleshooting. Here’s the short version. The original console uses a USB LAN accessory through the dock, while the OLED dock includes a built‑in LAN jack. Switch 2’s doc…  ( 8 min )
